Dried Blood Spots (DBS)
Sample collection at home − analysis in the lab
Dried blood has been used as a sample material for in vitro diagnostic analysis since the mid 1960s, especially in newborn screening and, over the past decades, has become a standard in this field. Moreover, dried blood is applied in drug screenings, doping controls and in therapeutic drug monitoring. It is also more and more used in antibody and antigen diagnostics. Therefore, EUROIMMUN developed the first CE-labelled blood collection set. It contains all materials that are required for collection and sending of dried capillary blood samples. Patients can collect the sample themselves from their fingertip by using the set, or the collection can be performed by medical professionals. The dried capillary blood samples are an excellent alternative to venous blood samples and can be analysed subsequently in the lab, e.g. for antibodies against SARS-CoV-2.
Sample collection at home by the patient possible
, no medical staff requiredSimple handling:
Capillary blood is collected by a prick in the finger, dropped onto the EUROIMMUN blood collection card and air-dried.Minimally invasive method
, a simple alternative to venous blood samplingSamples can be shipped by post without any additional cooling. High stability
demonstrated for a large number of analytesQuantification possible
, punches with a defined diameter allow exact determination of the collected blood volumeComplete automation of all process steps possible
Application

in combination with the ELISAs for the detection of IgG antibodies against SARS-CoV-2Feasibility studies performed for the determination of a large number of analytes
, e.g. vitamin D, antibodies against CCP, gliadin, Borrelia, measles virus, mumps virus, Rubella virus, TBE virus and Zika virus, as well as all allergens of the Atopy screen test (allergy)
