U. URINALYSIS
U.02. MANUAL URINALYSIS MICROSCOPIC EXAM
U.2.1. PRINCIPLE:
1. Routine Urinalysis consists of both physical and chemical
analyses to assist physicians in the diagnosis and treatment of
renal and urinary tract diseases and in the detection of metabolic
or systemic disease processes not directly related to the
kidney.
2. The microscopic examination of the centrifuged urine sediment
includes the study of formed elements, such as WBC’s, RBC’s, casts
and crystals.
3. The macroscopic examination of urine includes physical
appearance, such as color, character and clarity. See U.1 Manual
Urinalysis Dipstick SOP for macroscopic testing and reporting
procedures.
4. A qualitative chemical analysis of the urine is performed by
using a multi-parameter test strip that measure pH, protein,
glucose, ketones, bilirubin, urobilinogen, nitrite, blood,
leukocyte esterase, and specific gravity. The test strips are
dipped in the urine and read visually according to the color
comparison chart printed on the side of the container at prescribed
time intervals. See U.1 Manual Urinalysis Dipstick SOP for
qualitative testing and reporting procedures.
U.2.2.PURPOSE - The microscopic examination of urine
sediment.
U.2.3. SPECIMENS
1. Use fresh well-mixed urine collected by clean-catch method
into a sterile container.
2. The specimen should be unpreserved and uncentrifuged.
3. All urine specimens should reach the laboratory within one
(1) hour after collection and be properly labeled.
4. Urine specimens should be tested within two (2) hours after
collection. If urine cannot be tested within two (2) hours, it may
be stored for up to four (4) hours at 2 to 8(C. (The specimen must
be brought to room temperature before testing.)
5. The following urine samples are not satisfactory for
testing:
5.1. Specimens received over two hours after collection.
5.2. Mislabeled samples.
5.3. Improperly collected samples. For example, urine samples
with preservatives, specimens collected in non-sterile containers,
or specimens collected in containers with soap or detergent
residues will not be accepted.
5.4. QNS (Quantity Not Sufficient) - The recommended minimum
volume is 12 mL’s. The required minimum volume for microscopic
examination is 0.50 mL. In the event that less than <0.50 mL is
received, perform testing on uncentrifuged urine and comment as
noted in section U.2.7.
5.5. In the event that an unacceptable sample is received,
another sample must be requested. Document all action taken in the
LIS.
U.2.4.EQUIPMENT & REAGENTS
1. Equipment:
1.1 Kova System - Kova slides, pipettes & tubes
1.2. Centrifuge with timer
1.3. Microscope with 10x and 40x objectives
1.4. Lens paper or lint free tissues
1.5. Log sheets
1.6. Laboratory markers and pens
1.7. Clean gauze (4 x 4)
2. Reagents - None
U.2.5.CALIBRATION: Not applicable
U.2.6.QUALITY CONTROL:
1. Control Materials and Procedural Notes:
1.1. A Run in urinalysis is defined as all patient testing
performed in a 24-hour period. Quality Control must be performed
under the following conditions.
1.1.1. Every morning prior to testing patient specimens.
1.1.2. Whenever test results appear questionable.
1.2. A Normal and Abnormal Kova Control will be performed at
least once every run.(see above)
1.3. Reconstitute new Kova controls with 60 mL Reagent Grade
water according to manufacturer’s instructions.
1.3.1. After reconstitution, separate controls into 2 mL
aliquots using disposable transfer pipettes and plastic test tubes.
Cap tightly!
1.3.2. Label each plastic test tube with Normal or Abnormal Kova
Control, lot number, expiration date, reconstitution date, and
initials of tech who reconstitutes controls.
1.3.3. Sample aliquots will be stored frozen at -20(C. The
sample aliquots are stable at this temperature for up to four (4)
months.
1.3.4. Only one freeze/thaw cycle is permitted. Aliquots must be
at room temperature before testing. Do not use a warming block to
thaw.
1.3.5. Sample aliquots are stable for one hour at 15-20°C or 24
hours at 2-8°C.
1.4. Perform the Kova controls in the same manner as patient
samples. See section U.2.7 for the patient testing procedure.
Record the results on the Urinalysis Quality Control Worksheets.
See appendix 3 & 4.
1.5. All results must fall into the expected ranges, which are
obtained from the manufacturer’s insert for each control and
recorded on the top of the Urinalysis Quality Control
Worksheets.
1.6. If all results are within expected ranges, proceed with
patient testing.
1.7. If QC results are outside of expected ranges for
controls:
1.7.1.Re-examine the specimen using a different field of
view.
1.7.2.Adjust the coarse/fine focus as needed to improve the view
and repeat testing.
1.7.3.Check for signs of contamination in the controls.
1.7.4.Repeat the procedure with freshly reconstituted Kova
controls.
1.7.5.If the results are still out of range after performing the
above steps, notify the next higher supervisor immediately.
Corrective action must be taken and QC must be in range before
patient testing can be performed.
1.7.7.Record all QC values (both in and out of range) and
corrective actions on the Quality Control Worksheets, appendix 3
& 4.
1.8.Parallel Testing: All new quality control lots or separate
shipments of current lots will be tested against the current lots
for performance verification before performing patient testing. See
the Parallel Testing form, Appendix 5. Results are considered
acceptable if they are within their lot number quality control
limits.
U.2.7.PROCEDURE
1. Remove the specimens/controls from the refrigerator or
freezer, as applicable, and allow them come to room temperature for
at least 30 minutes before mixing.
2. Positively identify the specimens using the patient name and
date of birth.
3. Log the sample on the testing worksheet using the LIS
generated patient label, appendix 6.
4. Add the LIS generated label to the sample cup (not the sample
lid). Any discrepancy must be investigated before processing the
specimen.
5. Mix patient urine sample by swirling. Mix control aliquots by
inverting several times to ensure homogeneity of the contents.
6. If a macroscopic examination & urine chemistry testing is
ordered refer to U.01.1 Manual Urinalysis Dipstick Testing SOP for
testing and reporting procedures. The microscopic examination is
performed after dipstick testing unless the provider requests
otherwise.
7. If Clintest, Acetest or Ictotest is required as listed below
or requested by the provider, perform testing on uncentrifuged
urine prior to performing the microscopic exam. Refer to individual
confirmatory test SOPs as listed in the references.
8. The Clinitest confirmatory test is required for all pediatric
urine samples with patients age 2 years old or younger, regardless
of whether it was requested or not. See Clinitest SOP U06.1.
9. Backup tests and/or microscopic examination must be performed
on urine that tests positive for the following:

11.5.Urine specimens received from Physical Exam Clinic.
12. Pour 12-mL’s of specimen into a sterile Kova tube and label
the tube with the LIS specimen label. If the total specimen volume
is 0.50 mL or less, do not pour the sample into a Kova tube.
Perform testing from the specimen cup as indicated in the following
steps.
13. Testing
13.1. Volumes greater than 0.50 mL
13.1.1. Perform Dipstick, Clinitest, Acetest, or Ictotest as
required or requested.
13.1.2.Cap the Kova sample and centrifuge at 1500 rpm for 5
minutes.
13.1.3.Remove the sample from the centrifuge and discard the
cap.
13.1.4. If 3% SSA testing is required or requested, perform
testing on the supernatant according to the U.10.1. 3% SSA SOP.
13.1.5. Decant and discard the supernatant while retaining the
sediment pellet in the conical portion of the Kova tube. There will
be a small volume of fluid retained above the sediment. The total
volume retained in the Kova system tube after decanting the
supernatant should be approximately 0.5 mL.
13.1.6.Use a Kova disposable pipette to resuspend the sediment
pellet.
13.1.7. Proceed with testing in step 13.3.
13.2. Volumes less than 0.50 mL - swirl the sample in the
specimen cup to mix well.
13.3. Use a Kova pipette to aspirate sample from the well mixed
specimen.
13.4. Place one (1) drop of the sediment on the Kova slide so
that the urine sediment is drawn under the preformed Kova cover
slip.
13.5. Place the Kova slide under the microscope with the low
power objective (10X lens) and observe the sediment for the
presence of casts. Observe at least ten (10) fields and take the
average number of casts seen for each type.
13.6. Switch to high power objective (40X lens) to observe the
sediment for the presence of epithelial cells, WBCs, RBCs,
bacteria, crystals, yeast, trichomonas, mucus, and spermatozoa.
13.7. Scan approximately 8-10 fields and take the average per
field for each type of sediment.
13.8. QNS specimens - report the following canned comments as
applicable:
13.8.1. If the volume was <12 mL but > 0.5 mL, enter
[12ML] - Minimum specimen volume is 12 mL. Urine sediment results
may be falsely decreased due to a submitted sample volume less than
12 mL’s.
13.8.2. If the volume was <0.5 mL, enter [UNSPUN] - Testing
performed on uncentrifuged urine due to a submitted volume less
than 0.5 mL. Minimum required specimen volume is 12 mL. Urine
sediment results may be falsely decreased.
13.9. Review the results and enter data on the manual
microscopic patient result form (appendix IV). See section U.2.8
for Expected and Critical Results - Abnormal results will be
flagged.
13.10. Enter all results in the LIS. Do not certify any results
until all urinalysis testing ordered on the patient sample is
complete.
13.11. Urine samples are retained at 2-10°C for 24 hours in the
Hematology refrigerator.
U.2.8. EXPECTED / CRITICAL RESULTS & REPORTABLE RANGE:
1. The following bolded analytes require a result entry during
the microscopic results even if they are not seen during the
microscopic exam. Report “none” or 0-1 or 0-2 as indicated. All
other analytes are optional entry if seen during the microscopic

3. The presence of sperm in the urine of a female child under 16
years old is a critical value. Supervisor confirmation is required
before reporting any suspected sperm to the physician. The
physician must be notified in accordance with critical value
procedures before sperm is reported in the LIS. The urine must be
retained at 2-10°C until the patient’s physician and laboratory
director authorizes disposal. In no instance will the urine be
destroyed until duly authorized.
4. If a urine dipstick is performed, compare the results
obtained on the microscopic with the multi-parameter reagent strip
with the following facts in mind:
4.1.Urine with RBCs seen on the microscopic exam should have a
positive occult blood on the reagent strip.
4.2.Urine with casts should have elevated specific gravity and
positive protein.
4.3.Urine with crystals should have elevated specific
gravity.
4.4.Urine with positive nitrite should have bacteria on the
microscopic.
5. CRITICAL VALUES:
5.1. When the following values are encountered after a
urinalysis testing, immediately notify the physician or senior
ward/clinic nurse of the values encountered.

5.2. Critical values must be reported in accordance with the
laboratory critical value policy.
5.2.1. All critical microscopic sediment must be verified by the
laboratory supervisor before reporting to the physician/nurse and
before certifying results in the LIS.
5.2.2.All results must be read back by the physician/nurse and
the notification & read back documented in the LIS.
5.2.3.The pathologist must also be notified within 2 hours and
will determine if a pathologist review is required.
U.2.9. PROCEDURAL NOTES:
1. NORMAL CHARACTERISTICS OF THE URINE: The yellow color of the
urine is due largely to the pigment urochrome and small amounts of
urobilin and uroerythrin. Normal urine is essentially clear, and
the presence of particulate matter in uncentrifuged urine needs to
be explained microscopically. Normal urine has a faint, aromatic
odor of undetermined source.
2.Microscopic Sediment:
2.1. RBCs: Normally 0-2 RBCs/HPF may be seen in urine from males
and non-menstruating females. Increased numbers may indicate renal
hematuria.
2.2. WBCs: Normally 0-5 WBCs/HPF may be seen in urine of normal
males with slightly higher ranges in females. Increased numbers may
indicate renal disease or acute infection.
2.3. Epithelial cells: A few epithelial cells are normal and
indicate normal sloughing off of aging cells. Increased numbers may
indicate renal disease, urinary tract infection, or poor technique
in specimen collection.
2.4. Casts: 0-1 hyaline cast/LPF is found in normal urine.
Increased numbers or more advanced types indicate proteinuria.
2.5. Bacteria: A few bacteria are normally seen due to poor
technique in collection of the specimen. Increased numbers may
indicate kidney, bladder, or urinary tract infection.
2.6. Crystals: The following crystals may be seen in normal or
abnormal urine as noted below. Use urine pH and solubility
information (appendix 7) to aid in identification, as needed. Also
use appropriate image and literature resources to assist with
identification.
Normal
Abnormal
Acidic Urine
Alkaline Urine

Amorphous Urates
Amorphous Phosphates
Cystine
None
Uric Acid
Triple Phosphates
Tyrosine
Calcium Oxalate
Ammonium Biurates
Leucine
Calcium Phosphates
Sulfonamide (Sulfadiazine)
Calcium Carbonates
2.7. Mucus: Light mucus is normally found in urine and can
sometimes be confused with hyaline casts.
2.8. Spermatozoa: A few are normally found in urine from normal
males. Increased numbers are found in prostatic disease.
2.9. Trichomonas: Normally not found in urine. Presence of
trichomonas is abnormal and may indicate infection.
5.10.Yeast: 0-1/HPF or few per high power field are normal in
females. Increased numbers indicates infection.
5.11.Casts are classified according to their matrix, inclusions,
pigments and cells present.
5.11.1.Cast matrices:
5.11.1.1.Hyaline casts: Are translucent cylindrical structures
composed of mucoprotein. Increased numbers are seen with renal
diseases and transiently with exercise, fever, congestive heart
failure, and diuretic therapy.
5.11.1.2.Waxy casts: These differ from hyaline casts in that
they are easily visualized because of their high refractive index.
Waxy casts are homogeneously smooth in appearance. Their margins
are sharp, their ends are blunt, and cracks or convolutions are
frequently seen along the lateral margins. Waxy casts are commonly
associated with tubular inflammation and chronic renal failure.
They are also found during acute or chronic renal allograft
rejection.
5.11.2.Cast Inclusions:
5.11.2.1.Granular casts are semitransparent cylinders containing
small (fine) or large (coarse) granules. These granules represent
plasma protein aggregates. Granular casts appear with glomerular or
tubular diseases.
5.11.2.2.Fatty casts: Are semitransparent or granular cylinders
containing large highly refractive vacuoles or droplets. Visible
fat droplets are triglycerides or cholesterol esters. These are
commonly seen when there is heavy proteinuria and are a feature of
the nephrotic syndrome.
5.11.2.3.Crystal Casts: Crystalline inclusion in a
semitransparent or granular cylinder. These casts indicate
disposition of crystals in the tubule or collecting duct.
5.11.3.Cast Pigments:
5.11.3.1.Hemoglobin (Blood) casts: Appears yellow to red;
sometimes the color is very pale and difficult to interpret. These
casts are associated with glomerular disease.
5.11.3.2.Myoglobin casts: These cast are red-brown in color and
occur with myoglobinuria following acute muscle damage.
5.11.3.3.Bilirubin and other drug casts: Bilirubin is seen in
urine when there is obstructive jaundice, and will color casts as
deep yellow brown. Drugs such as phenazopyridine (Pyridium) cause a
bright yellow to orange color in acid urine and will color casts
and cells.
5.11.4.Cellular Casts:
5.11.4.1.Erythrocyte (Red Blood Cell) casts: Semitransparent or
granular cylinders containing distinct erythrocyte. Disorders
reflected in the presence of erythrocyte casts in the sediment may
include acute glomerulonephritis, IgA nephropathy, lupus nephritis,
subacute bacterial endocarditis, and renal infarction.
5.11.4.2.Leukocyte (White Blood Cell) Casts: Semitransparent or
granular cylinders containing leukocytes. They may be seen
pyelonephritis, glomerular diseases, interstitial nephritis, lupus
nephritis, and nephrotic syndrome.
6.SOURCES OF ERROR:
6.1. Urine should be tested within two (2) hours after
collection. Prolonged testing delay may result in cast dissolution,
RBC crenation or bursting, increased bacteria, and crystals
dissolution.
6.2. Fill the Kova slide chamber with the pipette placed
parallel to the slide and dispense the specimen drop in the corner
of the well. Samples placed in the center of the well can cause air
bubbles to form resulting in sample distortion during
examination.
