Why Hormone Blood Spot Testing

Why would I choose blood spot testing over blood serum testing?

Blood spot testing provides results that correlate extremely well to serum testing results in terms of accuracy, but without the cost and inconvenience of conventional blood drawing. There is no more wasted time and resources going to a lab for a painful blood draw as you collect your sample at home.

In preparation for our CardioMetabolic testing, for example, which must be done upon waking, blood spot testing is particularly convenient after an all night fast.

How do I collect a blood spot sample?

Within 30 minutes of waking, a few drops of blood from a quick and nearly painless nick of the finger, using the kit enclosed lancets, are placed on a filter paper. Once collected, allow your blood spot samples to dry for half an hour and then send them back to ZRT for processing. For more information, please see the Blood Spot Collection Instructions included with your test kit or watch the blood spot collection video.
