Dried Blood Spot Testing (DBST)

Dried Blood Spot Testing (DBST), pronounced as /draɪd blʌd spɒt ˈtɛstɪŋ/, is a method of collecting and storing blood samples for later analysis. The etymology of the term is straightforward, with "dried" referring to the process of drying the blood sample, "blood spot" referring to the small amount of blood used, and "testing" referring to the analysis performed on the sample.

Procedure

The procedure for DBST involves collecting a small sample of blood, typically from a finger prick, and placing it on a specially treated card. The blood is then allowed to dry, hence the term "dried blood spot". Once dried, the sample can be stored and transported at room temperature, making DBST a cost-effective and convenient method for collecting and storing blood samples.

Applications

DBST has a wide range of applications in both clinical and research settings. It is commonly used in newborn screening programs to test for various genetic, metabolic, and infectious diseases. It is also used in epidemiological studies, drug monitoring, and HIV testing.

Advantages and Disadvantages

The main advantages of DBST are its convenience, cost-effectiveness, and the ability to store and transport samples at room temperature. However, it also has some disadvantages, including the potential for sample degradation and the limited amount of blood that can be collected.
