The blood test should be performed after fasting overnight.
Procedure for LDL test
An LDL test requires only a clear sample of blood. This could also be called a venipuncture or drawing blood. It’s commonly done in the morning after 12 hours of fasting.
The healthcare provider will start by applying antiseptic to the region from where the blood will be drawn. Normally, blood is drawn from a vein in your elbow fold or at the back of your hand.
The medical professional will then tie an elastic band around the upper arm. That makes blood accumulate in the vein. A sterile needle is inserted into your vein, and blood is drained into a tube. You may experience mild to moderate pain that resembles a burning or piercing sensation. The discomfort will normally be lessened by calming your arm when the blood is being drawn.
A bandage will be applied to the wound once he/she is finished drawing blood. Pressure should be applied to the wound to help stop bleeding and prevent bruise. The blood is sent to a medical laboratory for LDL levels to be measured.
