What are the blood tests for which fasting is required?
  • Breath test: H pylori Urea breath test - SIBO Hydrogen breath test - Lactose breath test.
  • Cholesterol: HDL - LDL - Triglycerides
  • Glucose - Insulin
It is preferable to fast before any blood test but it is not mandatory, it depends on the tests.

How long should be the fasting period?
Usually it is required to stop eating and drinking 10-12 hours prior the blood test. Only one cup of water is tolerable.
Also note that the last meal before the fast should be light: no fried or fatty foods.

Are medication allowed before a test?
Usually no medication should be taken before the blood sampling; unless stated otherwise by your physician.

What are the steps to be taken if abnormal results show up in the final test report? Should they be repeated?
In case of abnormal results in the routine check up, we recommend you show them to your doctor. Each case is different and the treatment will be different. In some cases a slight change in the diet might be the solution but in other cases it requires a medical treatment. Repeating period can go from one week to 3 months depending on the abnormality and its severeness.

Does positive results in some cases (IDR - HIV - AgHBS - etc.) mean that I am sick?
Not necessarily. Here again each case is different and we recommend you meet with your treating physician prior judging. All positive infectious disease tests should be confirmed with another sampling and more advanced techniques in order to be given the final result therefore the adequate treatment.
