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. You can avoid wasted time and resources going to a lab for a painful blood draw, as you can now collect your sample at home.

Also, blood spot testing is beneficial in collecting your sample at particular times during the day. For example, our CardioMetabolic testing must be done upon waking after an all-night fast. Now you can take your sample first thing in the morning while warming up your morning oatmeal! No more light-headed driving to the doctor's office.

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.
