Dried blood spot (DBS) technology is a very simple and inexpensive technique for collecting drop(s) of whole blood on filter paper. DBS has been in existence for almost 50 years but has gained interest recently due to advancements in technologies that enable sensitive and reliable methods for collecting quantitative data from a drop of blood samples.
An FDA cleared, novel blood test to help assess a woman’s menopausal status and assists in estimating the time to the final menstrual period. Dried blood spot sampling means that physicians can mail the sample collection devices to the patients that are remote. It also allows for easier serial sample collections and it greatly simplifies the storage, preparation, and transportation of samples.

SARS-CoV2 IgG and IgM:
The advantage of antibody immunoassays is the ability to detect recent and past infections. This test has the advantage of detecting not only individuals with active infection but also those who were previously exposed to the virus and may have subsequently developed immunity. The dried blood spot sample is significantly easier and more comfortable than collecting nasopharyngeal specimens. It is also much more stable and doesn’t require a specific collection tube.
