The effect on colloid osmotic pressure (COP) of heparinizing body fluids was estimated with a low compliant osmometer, using Diaflo PM-30 or PM-10 membranes (Amicon, Lexington, Mass., USA). It was found that collecting and storing samples in preheparinized glass capillaries may increase COP by up to 4.0 mmHg. Measurements on heparin and protein solutions… CONTINUE READING
