Change from baseline to Day 10 in mean absolute lymphocyte count
Ramy czasowe: 10 days
|
For each assessment, 1.5 mL of blood was collected aseptically from the subject in the supine position by venipuncture or via an intravenous.
catheter placed in an antecubital vein in the arm in ethylenediaminetetraacetic acid containing tubes.
Immediately following collection of the required whole blood volume, the tubes were slowly tilted backwards and forwards (no shaking) to bring the anti-coagulant into solution.
The anticoagulated whole blood stored at room temperature (20-25 °C) was preferably stained within 12 hours, at the latest 24 hours, and analyzed within 24 hours.
The lymphocyte counts were determined with standard commercially available assay kits.
