Most Chxhealth panels are taken as a venous blood draw at one of our clinics. A small number of standalone tests are available as at-home finger prick kits. Each method has its place.
Why most panels use venous blood
A venous draw collects enough blood for a comprehensive multi-marker panel. Hormone tests, large biomarker panels (Standard Screen, Biohacking, Sports Performance, etc.) and most genetic tests require the volume that only a venous sample provides.
When finger prick is appropriate
Finger prick is suitable for some specific single-marker or small panels. The Chxhealth At Home PSA Test uses a finger prick kit, sent to your home and returned to the lab by post. Some urinalysis options are also at-home.
Accuracy
Both methods, processed by an accredited lab, are accurate for the markers they test. The difference is breadth (venous supports many more markers per sample) and convenience (finger prick can be done at home).
What to choose
If your panel is large, comprehensive or includes hormones, it will require a venous draw. The phlebotomy fee is included in the price. If it is a focused single-marker test like PSA, an at-home kit may be available. The product page tells you which applies. Chxhealth is a biomarker and genetic data provider.

Frequently asked questions
Are finger prick tests less accurate?
No, when processed by an accredited lab. The constraint is volume, not accuracy. Finger prick can only support specific test types.
Can I do the Standard Screen as a finger prick at home?
No. The Standard Screen requires a venous blood draw at a clinic because it covers many biomarkers. The phlebotomy fee is included in the price.
