What are dried blood spots?
Dried blood spots are samples of blood collected on filter paper, used for analyzing biomarkers.
How is DBS collection performed?
The process involves warming the hands, cleaning a finger, puncturing it, and collecting blood on filter paper.
What are the advantages of DBS over venipuncture?
DBS is less invasive, easier to collect, and can be done in various settings.
What precautions should be taken during collection?
Use personal protective equipment and ensure proper hygiene to avoid contamination.
How long does it take to collect a DBS sample?
Once mastered, the DBS collection process can be completed in less than 10 minutes.
What types of biomarkers can be analyzed from DBS?
DBS can be used to analyze cholesterol, C-reactive protein, and glycosylated hemoglobin, among others.
