Fasting Tests
Some blood tests require fasting before the sample is taken. Fasting means that you should not eat or drink anything except water for at least 10 hours before your scheduled test time. However, drinking a glass of water is allowed during the fasting period. Any medications should be taken as usual unless your doctor has given you other instructions.
Fasting for a test means that you:- should not eat or drink (except for 1 glass of water) 10 hours before the test
- can take any medications unless instructed otherwise by your doctor.
If you are scheduled for a test at 08:00 AM, you should not eat or drink (1 glass of water is allowed) for at least 10 hours before the test, meaning your fast should start at 10:00 PM the night before.

Diurnal Variation
Some tests do not require fasting but may need to be taken before a certain time, such as 10:00 AM, due to significant diurnal variation in the value.
If your test requires submission before 10:00 AM, this will be detailed in the information for the health check, health package, or health test you have purchased.
Why do I need to rest for 15 minutes before the test?Most reference values that test results are compared against are obtained from individuals who have sat down and rested for 15 minutes before their sample was taken. To ensure your values are accurate, it is important that you plan your visit so you have the opportunity to rest for 15 minutes before your test at your chosen sampling unit.
Medications and Supplements
When taking blood tests, it is important to be aware of how medications and supplements can affect your results. Levaxin, a medication for thyroid issues, should be taken after your test to avoid inaccurate results. Hormone medications and dietary supplements can also affect the outcomes. Contact your doctor if you are unsure about how your medications and supplements affect your test results.
If your test has specific guidelines regarding the intake of certain medications or supplements, this will be stated in the information for the health check, health package, or health test you have purchased.
