Comments

This test includes neopterin as well as biopterin. In order to run this test as a profile, both the urine and blood spot cards must be sent for testing. Keep away from direct sunlight and heat. Protect urine from light during collection, storage, and shipping. Submit frozen urine and room temperature blood spot card if both samples can be collected during the same visit. If there is a delay in collecting a urine specimen, allow blood spot card to dry for 3 hours at room temperature, place in bag, and then freeze the blood spot card. 

There is the ability to test for biopterin or neopterin separate from this profile, but they would need to be a XMIS test. This test is not set up to handle that request. The Sendout lab would have to order those tests as individual tests to the reference lab.
