Abstract:

The immunofluorescence test, carried out on 930 samples of total dried blood absorbed on disks of Canson No 435 blotting paper, has furnished results that were identical with those obtained with the serum, in regard to both sensitivity and specificity. The preservation of the reactivity of the disks of dry blood is perfect during a minimum period of six months at laboratory temperature 20-25 deg C and even at higher temperatures 43 deg C. The importance of this method resides mainly in the simplification of the method of taking the blood sample, which can be carried out without venous puncture, merely by puncturing the tip of the finger and also in the ease of transportation of the samples, which, placed in a plastic bag, can travel in the form of a simple letter, without the danger of breakage or hemolysis which exists when a tube of blood is being shipped.
