Phlebotomy vs finger prick blood sample collection

All our tests use a finger prick method of blood sample collection. A finger prick blood test (also known as capillary) is one that is collected from the finger using a lancet that pricks the finger with a small, sharp needle.

We also provide an option for you to have a phlebotomy blood draw. A phlebotomy blood sample (also known as venous) is where the blood is collected from the vein. 

Both phlebotomy and finger prick blood samples are accurate ways of measuring your body’s key biomarkers.

As each collection type follows a different method of blood extraction the results won’t be identical, just as venous samples analysed at two different labs won’t have identical results. 

However, independent research we’ve undertaken in collaboration with the University of the West of England found very little difference between venous and capillary sample types.

If you want to monitor your biomarkers we would recommend that you keep with the same methodology as reducing the variables will allow you to establish an accurate trend.
