RBC Glutathione Reductase (GSHr) [can also be measured in plasma if requested]
[Green top heparin tube, sample must reach laboratory within 24 hours]
£21.00
Glycosylated Haemoglobin (HbA1)
[Lavender top EDTA tube]
£18.00
Haemoglobin
[Lavender top EDTA tube]
£9.00
Histamine
[Green top heparin tube]
£25.00
At raised levels this amino acid has been shown to be a risk factor for coronary heart disease, stroke and peripheral vascular disease. Levels are influenced by diet, and in some cases genetic factors. B vitamin supplementation reduces homocysteine levels.
[EDTA - specially prepared tube available on request for postal samples]
£40.00
Indicans (qualitative)
[Early morning urine sample]
£13.00
Iron and total iron binding capacity
[Gold top tube (SST)]
£18.00
Total iron binding capacity
[Gold top tube (SST), Note: Sample should be taken without venous stasis]
£11.00
Kryptopyrroles (semi-quantitative)
Note: Add an eighth of a teaspoon of ascorbic acid to the urine sample as a preservative.
[Mid-stream urine sample - preferably collected in the afternoon or evening]
£14.00
Serum Paraoxonase
Serum paraoxonase (PON-1) is an antioxidant enzyme whose activity is associated with a decreased atherosclerosis risk; its measurement may therefore give useful information as to a subject’s cardiovascular risk. Since PON-1 is induced in oxidative stress, careful assessment of its serum activity is indicative of the subject’s ability to metabolise organophosphates and other xenobiotics.
[Green top heparin tube or Gold top tube (SST)]
£21.00
RBC peroxide fragility (H2O2) - functional test for vitamin E status.
[Patient must attend the laboratory]
£15.00
Sulphites - functional test for molybdenum status
[Early morning urine sample]
£13.00
Superoxide Dismutase (RBC) - an important antioxidant enzyme and functional test for copper status. (Download datasheet)
Why measure superoxide dismutase?
[Green top heparin tube]
£23.00
Urine Routine urinalysis (chemistry & deposit) – see London Clinic tests for culture and sensitivity.
[Mid-stream urine sample]
£14.00

[Patient must attend the laboratory, no food from midnight the previous evening]
£46.00
5.0 hour (9 samples)
[Patient must attend the laboratory, no food from midnight the previous evening]
£67.00
Zinc challenge tests:
1.5 hour (2 samples)

£46.00
Lactose Absorption Test (see also breath hydrogen test)
[Kit required from the laboratory, no food from midnight the previous evening]
£41.00
D-Xylose Absorption Test
[Kit required from the laboratory, no food from 10pm the previous evening]
£23.00
D-Xylose Absorption - Pre/post gluten challenge
[Kit required from the laboratory, no food from 10pm the previous evening]
£46.00
Magnesium Loading/Retention Test
A 24-hour urine magnesium level is measured, before and after an intramuscular magnesium load. There is an increased retention of magnesium when a deficiency exists.
The patient brings the first 24-hour urine sample to the laboratory, has the magnesium injection adn then proceeds to collect the second 24-hour urine sample.
[Kit required from the laboratory]
£30.00
