Frequently Asked Questions

What are venous blood tests for?

Home test kits are highly accurate when used correctly. They are processed in certified labs using the same standards as in-clinic tests.

Who is a phlebotomist?

A phlebotomist is a trained healthcare professional who specializes in collecting venous blood samples for testing. The Phlebotomists ensure safe, sterile, and accurate blood draws using proper techniques and equipment.

How much blood is taken during a phlebotomy?

Typically, a venous blood test requires just a small sample, usually one or two vials (around 5–10 ml each). In therapeutic phlebotomy (for treatment purposes), a larger amount may be taken, up to 500 ml. The amount depends on the type of test or medical requirement.
