Design outcomes

Primary

Measure	Time frame
Test persons and patients are given blood in different tubes containing different anticoagulants on one day. On the one hand, T-cells will be directly examined by FACS analysis with regard to sensence. Another part of the blood is sent under controlled conditions for about 24 hours and then examined in the same way. Thus, the effect of the transport on the T-cell analysis will be investigated.	—

Secondary

Measure	Time frame
The most suitable anticoagulants for the direct analysis of T-cell senescence and for analysis after transport.	—
