The glass bead column method for determining platelet adhesiveness is described. The method is a modification of the original technique of Salzman as follows.
A nylon tubing containing glass beads was connected with a first syringe using a three-way stopcock. Test blood sample (being filtered) as well as control blood sample was drawn using one needle, which was attached to the other side of the stopcock. The test blood sample was collected through glass bead column into a second syringe which contained 3.8% citrate and was distally connected with the nylon tubing. The filtration rate of test blood sample was 2.7 ml/30 seconds.
Platelet factor-3-activity as well as its availability and adenine nucleotide contents in filtered platelets was not significantly different from those in control platelets. Platelet aggregability was slightly increased after filtration through glass bead column.
