17 α OH Progesterone
Serum or lithium/heparin plasma 0.5mL 2 weeks 0-6 nmol/L Neonatal samples should not be taken in the first 48 hours
of life. 2 weeks
17 α OH Progesterone (in
blood spots) Blood spot 1 month For monitoring only
3 spots collected throughout the day
1 month
Acid-Base status
Paediatrics: pre-heparinised syringe, 0.5mL
minimum or full heparinised capillary tube. Mix well
immediately after collection to prevent clotting.
Adults:
Blood gas syringe. Remove needle, cap syringe.
0.5mL 30 min
pH: 0-28d: 7.18-7.51
1-5 months: 7.18-7.50 6-11 months: 7.27-7.49
>=12 months to 17 years: 7.35-7.45 Do not send this specimen by
pneumatic tube.
Send labelled sample on ice to the laboratory
immediately after collection. Inform the laboratory before you send a gas. Capillary
samples require proper collection technique to ensure reliable results
AFP can also be measured in other fluids (not urine) but these reference ranges do
NOT apply.
Increased AFP levels can be caused by liver
cancer, germ cell tumour of the testis or less commonly other cancers (for example, stomach, bowel, lung, breast, lymphoma). Slightly increased levels of AFP are
common in patients who have chronic
hepatitis or cirrhosis and do not indicate the
presence of cancer.

Breath hydrogen Collected by lab staff
Hydrogen breath tests involve the administration of either lactose or sucrose in order to identify malabsorption, or the synthetic sugar lactulose in order to determine gut transit time and/or small bacterial overgrowth. Fructose testing is not provided as a large proportion of the population give positive results. At rest no physiological processes produce hydrogen gas, and so the basal values of a normal patient are low, approx. 0-5 ppm. In health the H2 in the breath should remain <20ppm throughout the test and no symptoms should be observed. In positive tests (due to primary saccharidase deficiency or secondary cause(s) basal fasting values should also be <10 ppm. The H2 levels measured in the breath increase to >20ppm after approximately 60 minutes as the sugar reaches the colon and is metabolised. The value should continue to increase to the end of the test. An early peak (<1hr) may indicate small bowel bacterial overgrowth. Lactulose is not broken down in the small intestine in health, instead progressing through to the colon where it is hydrolysed and fermented by bacteria producing hydrogen. In small intestinal bacterial overgrowth, bacteria from the colon overflow and grow in the small intestine. In a negative test lactulose will produce a hydrogen peak after approximately 120 min as the lactulose load reaches the colon. This timing gives some idea of gut transit time.In a lactulose test positive for small bacterial overgrowth, lactulose is metabolised by the excess anaerobic bacteria in the small intestine resulting in an earlier peak in expired hydrogen with a second peak about 15 min later from the normal colonic lactulose fermentation.
Patients should not have received antibiotics in the preceding 2 weeks. High
baselines maybe observed if the patient has failed to fast or not adhered to a low fibre diet before the test.

Calprotectin Random faecal collection 5g
Sample should be sent promptly to the
lab
Faecal calprotectin concentration <50ug/g wet weight excludes active bowel inflammation with a high degree of confidence. Note that conditions other than IBD (e.g., infection, neoplasia, NSAID treatment) may raise calprotectin. This test should not be used in cases of suspected colorectal cancer. Faecal calprotectin concentration of 50ug/g to 70ug/g is equivocal. Repeat in 4 weeks and refer to Gastroenterology if the repeat level is equal to, or greater than 50ug/g. Faecal calprotectin concentration >70ug/g indicates active bowel inflammation. Refer to Gastroenterology.
Samples collected while the patient has diarrhoea may give falsely low results.

Optical Density Difference
(ODD) Amniotic fluid in a plain container 5.0mL
Must be protected from light and lab needs prior
warning.
Pregnancies affected by Rhesus incompatibility lead to the destruction of
foetal red cells in utero. The bilirubin produced in this process passes into the amniotic fluid where it can be measured
by determining the optical density difference (ODD) at 450nm.
Results require specialist interpretation.
There are many potential confounding
factors. Please discuss with the lab before proceeding.

Serum P3NP levels in children may reflect
both hepatic fibrinogenesis and also general growth. No guidelines for further investigations are currently available in
children.
Consider biopsy in psoriatics on
Methotrexate if Pre-treatment >8.0ug/L or
three samples > 4.2ug/L in twelve
month period or two samples > 8.0ug/L
consecutively. Consider withdrawing Methotrexate if three
samples > 10.0ug/L in a twelve month period. Active erosive arthritis or fractures may raise
