The following instructions must be followed:
You are advised to collect the sample of urine using the "clean-catch" technique:
This is used to evaluate diabetic patients and to assess the potential of early onset of nephropathy before overt proteinuria develops. Here, a second morning urine collection is performed. The patient must rest prior to the collection of the sample.
Urine is collected over a 24 hour period into a can provided by us. You will be instructed by the staff at the Melsta Laboratories collection centre on the requirement to be met in order to complete the test, including substances to be avoided.
Eg:- The patient should strictly avoid alpha-methyldopa, buspirone, codeine, isoproterenol metabolite, Mandelamine, L dopa, paracetamol, metoclopramide, pepper, alcoholic beverages, tea/coffee tobacco and strenuous exercise at least 72 hours prior to and during specimen collection.
Thirty minutes of rest is required prior to the collection of the blood sample. It is advisable to adhere to a low carbohydrate level diet along with a normal salt diet (3g/day) for at minimum duration of 2 weeks prior to the test. Adhere to this diet 30 days prior to the test if possible. Do not consume liquorice for a minimum of 2 weeks prior to the test.
This test is conducted twice a day; first at 8.00 am when the cortisol levels are at its peak followed by the second testing at 4.00 pm when the cortisol levels are much lower. The test can be conducted with either a urine or saliva test.
OGTT is used to diagnose diabetes mellitus where random or fasting plasma glucose concentration is inconclusive in reaching a diagnosis. This test is also used during pregnancy to diagnose gestational diabetes (GD1v1) in women who are in a high-risk group during this period.
