When The Tamarac® Test is used in conjunction with a single-drop, point-of-care (POC) hemoglobin instrument, the first two drops from the stick site are used for the lead test, and the third drop is used for hemoglobin measurement.  As a result, both mandated EPSDT blood tests are performed with a total of only 3 drops of blood from a single stick – the same amount of blood that would be required if hemoglobin testing was done alone.
