Blood Sample Collection Procedure:

* Inform healthcare provider: Disclose any needle phobia, blood-related nausea, or allergies to latex or plaster.
* Sit or lie down: Position yourself comfortably for the procedure.
* Tourniquet placement: A band is applied around your arm to tighten the vein.
* Fist tightening: May be necessary to enhance vein visibility.
* Vein selection: A suitable vein is identified for blood extraction.
* Needle insertion: A small needle is inserted into the vein after cleaning the skin.
* Blood collection: Multiple small bottles may be filled with blood extracted from your hand or arm.
* Needle removal: Once sufficient blood is collected, the tourniquet is released.
* Wound care: Pressure is applied to the injection site using a cotton ball or gauze to minimize bleeding and bruising.

Importance of Hemoglobin A1C and DHEA Tests:

Hemoglobin A1C:

* Provides an overview of blood sugar control over the past 2-3 months.
* Helps predict heart disease risk in individuals with and without diabetes.
* Low levels occur with age.
* Optimal levels are crucial for preventing diabetes complications.

DHEA:

* Known as the "antiaging hormone," it peaks in the 20s and typically declines thereafter.
* Low DHEA levels are associated with impaired erectile function, immune function, wound healing, bone density, abdominal fat distribution, and mood.
