Dried Blood Spot Laboratory

Easy use

Finger prick

Finger prick procedure

  • A finger prick creates minimal discomfort.
  • Only a very small amount of blood is sampled.
  • Particularly suitable for use in children, the elderly or obese patients.


Dried Blood Spotting, DBS, is a widely accepted micro blood sampling method in which the patient, volunteer or participant in a study is pricking her/his finger and a drop of blood is applied to a specifically prepared carrier. A drop of blood, ~ 30 microliters, is about a 330 times smaller volume compared to a traditional blood sample (10mL). This makes DBS the method of choice when the blood volume sampled should be kept to a minimum or when obtaining a venous blood sample is an issue.

The Blood Spot card is returned in a special envelope to DBSL for analysis. Accurate determination of blood levels of biomarkers and other components in a single drop of blood has become possible by technological innovation, especially by the availability of state of the art equipment for mass spectrometry. The sensitivity of this type of equipment has increased a 100 to 1000 fold in recent years, developments that have made it possible to perform a full quantitative determination of the desired components with sufficient accuracy in a dried blood sample. Operation of the laboratory instrumentation requires highly trained and experienced staff. The analytical applications are developed using the latest state of the art.
