Collecting dry blood spot (DBS) samples is a relatively straightforward process providing instructions are followed and samples are not contaminated before drying. DBS sampling is used in many applications and offers several advantages over the typical venous blood collecting methods. This blog post will cover how a dry blood spot sample is collected and what applications benefit from this method.
Dry (or dried) blood spot (DBS) sampling is a method of bio-sampling in which blood samples are spotted and dried onto absorbent filter paper. Although DBS is a method that was first mentioned in 1913, it has become more prominently used since the 1960s because samples are easily stored at room temperature. Other benefits are the procedure is less invasive and reduces the risk of infection to a minimum.
All of our DBS sampling cards at RDA Spot come with clear instructions, which can also be downloaded from our website. The blood samples can be obtained by pricking a fingertip and allowing a few droplets of blood to saturate the paper. Once dried and packaged safely, these samples are sent to a dedicated laboratory where tests are carried out.
DBS sampling has been used in many applications over the last 30 years. These applications include communicable diseases, drug studies, environmental research, forensics, toxicology and other research.
This blood sampling collection method is a way to safely and conveniently diagnose infectious diseases as well as being favored for drug research and development in the pharmaceutical industry.
