Whole bloodThe analysis of the fat-soluble vitamins A and E and lipid micronutrients in blood, such as carotenoids, is an important parameter to monitor the micronutrient status in humans. Although the potential of dried blood spot (DBS) cards, the use of this technique for blood sampling and...
The invention relates to a dried-blood-spot-card shipping and storage container, the container comprising at least one compartment, the at least one compartment being adapted to receive at least one dried-blood-spot-card (3) and being openable and being air-tight closable with a closure, pref...
Human serum samples of 10 μl loaded onto the card were extracted at two different dilutions - 1:20 and 1:50 in Opti-MEM. VN testing was performed from these starting dilutions and titers were compared to corresponding dilutions of frozen serum in the same 96-well plates: 24-h, 96-h...
