Capitainer launches new blood self-sampling product

Swedish medtech company Capitainer has launched a new product for the self-sampling of blood. The sampling card can collect five times as much blood as its predecessor.

The product extends Capitainer's range and market opportunity by enabling more and other types of analyses. It is also easier for laboratories to implement. 

Capitainer is launching a self-sampling card that collects and stores a larger amount of blood (2 x 50 microlitres), complementing its predecessor (2 x 10 microlitres). This makes it possible to measure more biomarkers in the blood from the same sample and offers a broader range of analyses, as some substances require a larger amount of blood for the analysis to be accurate. 

Capitainer's products for self-sampling are based on the patient themself (or with assistance) collecting blood using a unique sample card. The card absorbs a precise amount of blood that is dried in a protected paper disc. The sample is then sent by regular mail to the laboratory for analysis – no need for refrigerated transport or special packaging. 

A larger sample volume means better compatibility with existing laboratory assays, processes, and equipment. 

CEO Christopher Aulin said: "It means that more laboratories will have the opportunity to analyse our samples. It will be easier to implement and take advantage of our smart self-sampling solutions, and it offers new opportunities for rural areas in developing countries.” 

The new product, Capitainer B 50, enables analyses requiring larger blood volumes for accurate analytical sensitivity. These include quantitative PCR, which is measured in, for example, HIV and hepatitis. The new product can also be used to analyse substances that occur in low concentrations, such as doping substances. 

Capitainer develops a complete platform for self-sampling blood, plasma, and urine. On the market today are Capitainer B (blood) and Capitainer B Vanadate (a card developed to enable a correct analysis of PEth, an essential marker for long-term alcohol intake/abuse).
