🤔 What Is a Plasma Test?
Blood is comprised of many components including red blood cells, white blood cells, platelets, and plasma. Plasma is the liquid portion of blood - the portion that is not the cells or platelets - and is collected with an anticoagulant in the collection tube.
The base blood draw is the same for any phlebotomy test (whole blood, serum, plasma); the treatment of the sample post-collection is what makes a test a whole blood vs. serum vs. plasma test.
For a plasma test, an anticoagulant is part of the collection tubes; a centrifuge is not required.

All phlebotomy tests require a blood draw by a phlebotomist. Draws can be completed in clinics or via mobile phlebotomists that can usually come to your home or place of work.
The phlebotomist will likely follow the general process documented:
Look at your veins (inside your elbow) to determine the best to use for the blood draw
Place a tourniquet on the arm that will be used for the blood draw
Clean the area in question with an alcohol pad
Use a needle to get blood; draw and fill the applicable tubes provided for each respective test
Place a bandaid where the needle was after the blood draw is complete
Detailed directions are provided in the kit and phlebotomists should review these review them prior to the blood draw and leverage to complete the draw!

📬Shipping my sample
Phlebotomy blood samples have an expiration date!!!
Read kit instructions and pay special attention to shipping requirements
Some labs provide specific days of the week for when samples should be drawn and shipped due to time sensitivity for sample viability
Prepaid shipping labels are included in all kits
Completed tests typically require a drop off at FedEx or UPS
We recommend going to an actual store location versus a drop box to avoid any complications around pick-up times for shipping
💪Will I feel bad?
Blood draws do require a needle - but blood draws typically don't take too long and a small amount of blood is taken
The typical amount of blood taken for a blood test is ~3ml, while a complete blood count (CBC) or complete metabolic panel (CMP) is 10ml. Keep in mind the average person has between 4,500 - 5,700 ml of blood 🙂
Given the amount of blood taken in a blood test, most folks don't feel bad after the test. However, you know yourself best! Take whatever precautions feel right to you!
