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 required
- Simple 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 sampling
- Reduction / elimination of biological risks: According to the US Department of Transportation (DOT), the International Air Transporter Association (IATA) and the World Health Organisation (WHO), dried blood spots are released medical specimens which do not require any special protective measures.
- Samples can be shipped by post without any additional cooling. High stability demonstrated for a large number of analytes
- Quantification possible, punches with a defined diameter allow exact determination of the collected blood volume
- Complete automation of all process steps possible
- Application of DBS samples validated in combination with the ELISAs for the detection of IgG antibodies against SARS-CoV-2
- Feasibility 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)
