6. A small amount of blood will be collected into a vial or syringe.
7. After collecting the sample, the tourniquet will be released.
8. Pressure will be applied to the puncture site with a cotton ball or gauze to stop bleeding and bruising.

Variability in Test Results:

Different laboratories may use varying equipment and methods, leading to different standard normal results.

Hemoglobin A1C Test

* This test measures blood sugar control over the past 2-3 months.
* Recommended every 3-6 months for people with diabetes.
* Maintaining optimal hemoglobin A1C levels can reduce the risk of diabetes complications.
* This test can also predict heart disease risk in both diabetics and non-diabetics.

DHEA (Dehydroepiandrosterone)

* Known as the "antiaging hormone," DHEA levels peak in the 20s and decline with age.
* Low DHEA levels can impact erectile function, libido, immune function, wound healing, bone density, and mood.
