🤔 What Is a Blood Spot Test?
A blood spot test or 'Dried Blood Spot' is a blood test that a patient can collect themselves at their convenience. A patient will use the lancet provided in the kit to prick their finger and place blood drops on the provided card per instructions included in the kit.
The card with dried blood spots are then analyzed per specifications of the test. These are commonly used for measuring hormones, vitamin D, thyroid, and insulin.
📝 How Do I Complete a Blood Spot Test?
This test can be completed without a phlebotomist. Instructions will be provided with the kit that is sent to each patient. Typical kits include medical gloves, alcohol prep pads, bandaids, lancet, and gauze pad, in addition to the collection card and specimen bag.
In general, directions will generally advise patients to:
Be well hydrated
Do arm exercises or warming your hands to increase blood flow
