Blood Spot Testing

Kirkman is NOW Distributing Purity Labs Testing


What is Blood Spot Testing?

Purity’s blood spot testing is an easy, minimally invasive test. The patient will prick their finger and transfer blood from their finger onto a testing strip. The strip will then be sent back to Purity where it will be analyzed for the patient’s vitamin D status. The test will look at both vitamin D-2 and vitamin D-3 levels, the two most important types of vitamin D in humans.

Robert Guthrie introduced blood spot testing in 1963 and it has been used around the world to test infants for phenylketonuria. This was due to the fact that a blood draw was not realistic for babies. This way of testing has now expanded analysis for vitamin D, hormone levels, hypothyroidism, HIV and many others.

The Blood Spot Testing Kit

The blood spot kit contains all the tools necessary to perform the test. It includes instructions on how to take the test, two lancets, a spot saver card, an alcohol prep pad, a surgical sponge and a latex free bandage. A requisition form and pre-paid return envelope are also included in the kit. When the test is complete it is placed into the pre-paid envelope along with the test requisition form and mailed back to Purity.
