What Glycan Determinants measures
Glycan Determinants is most often requested in connection with sugar Molecules, carbohydrate Structures and glycoproteins, which is why it sits within the laboratory tests group at Wimpole Street.
This test measures a specific substance, enzyme, protein or cellular feature in the sample provided, and is usually requested to answer a particular question raised by symptoms, another result or a specialist’s assessment. Some tests in this group are highly specialised assays run by reference laboratories, others are components more often seen inside a larger profile. The product description above gives the specific parameter, sample type and turnaround.
Preparing for your Glycan Determinants
- 1Most tests need no special preparation; where fasting, timing or medication adjustments matter, the product description or the nurse will say so.
- 2Bring a list of your medicines and supplements, since several assays are influenced by them.
- 3If you are unsure whether this is the right test for your question, contact the clinic before booking and the nurse can advise or suggest an alternative.
Sample for this test: venous blood sample (serum).
Understanding your Glycan Determinants results
Your result is reported against the laboratory’s reference range for your age and sex, and any value outside that range is flagged on the report. Specialist assays sometimes have narrow clinical uses, so the result is best read in the context of why it was requested. We do not provide clinical interpretation; a result is not a diagnosis, and its meaning depends on your history and symptoms, so discuss it with your GP or a clinician.
Laboratory values are one part of a clinical picture, and any unexpected result should be discussed with the clinician who is looking after the wider question.
