What is BloodSpot testing?

The name refers to the collection process in which the patient collects drops of blood from a fingerstick into a small collection tube (microtainer). The tube is treated in exactly the same manner as a traditional blood collection tube once it arrives at the laboratory for testing.

How does BloodSpot testing work?

The patient is given a kit containing materials for the collection and shipping of their specimen. They perform a fingerstick on themselves with a lancet (similar to the procedure for glucose testing) and collect the blood into a small serum separator tube. Depending on the number of tests ordered, one or two tubes may be required. Once collected, the specimens are sent to us next day via U.P.S. In the lab, the tubes are spun and serum aliquoted for testing in the same manner as larger blood collection tubes.

What are the advantages of BloodSpot testing?

The convenience and stress free collection for the patient is a main advantage. No trip to a physician’s office, no stressful or painful venipuncture; it’s all performed in the comfort of the patient’s home when the time is right for them. The volume of specimen required is considerably less than that of a venipuncture-each tube holds 600 microliters, compared to the 8mL of a “traditional” SST tube. After collection, they just place the specimen in the provided shipping package and drop off at a UPS pickup area or have it picked up.

An even more important advantage of BloodSpot testing is its accuracy. Extensive studies were performed to determine the validity of BloodSpot results compared to traditional venipuncture specimens. Results show the same precision as serum testing.
