Are there cost differences between dried blood spot over serum blood biomarker assays?

08 March 2018 1 4K Report

The cost estimates of a planned study are mainly based on serum blood. However, to reduce particiants burden, we would like to choose dried blood spot. Therefore, it would be very helpful if anyone could provide some approximate cost estimates for assaying the following biomarkers via DBS:

- zinc ($5 ??)

- transferrin

- Vitamin A & D ($3 each ???)

- IL-6, TNF-alpha, CRP, leptin ($ 9.5 ???), adiponectin

Thank you very much.

Muhammad Adnan

I think there should be no cost differences, but I would prefer serum estimation than DBS, because of sample retrieval, limited whole blood assay availability, micro sample errors etc.
