0 [micro]L) and to measure PCV by the microhematocrit
tube method (50 [micro]L).
Other hematocrit methods such as direct hemoglobin determination using a drop of fingerstick blood in a miniaturized cuvette provide excellent bedside testing substitutes for the spun microhematocrit
Key words: plasma biochemical analysis, centrifugation, microhematocrit

I thought every lab in America had an old reliable microhematocrit
centrifuge on hand.
2-mm-diameter heparinized microhematocrit
tubes to determine the PCV and TPS concentrations.

Ejaculated fluids were collected in dry nonheparinized microhematocrit
The groups' own list eliminates the following: spun microhematocrit
, microscopic exam of urine sediment, vaginal wet mount preparation, whole blood clotting time, ASO screen, CRP screen, rheumatoid factor screen, Gram stain, infectious mononucleosis screen, KOH preparation on cutaneous scrapings, and semen analysis.
After blood smears were prepared and samples collected into microhematocrit
tubes to measure packed cell volume (PCV), the remaining blood samples were centrifuged at 16 000g for 5 minutes to separate the cellular fraction from plasma.
Leukocytes Urobilinogen * Fecal occult blood * Spun microhematocrit
* Microscopic examination of:
To estimate PCV, blood samples were placed into plain microcapillary tubes (Bilbate Ltd, Daventry, UK) and centrifuged at 10 000g for 5 minutes in a microhematocrit
centrifuge (Thermo Electron Corporation, Langenselbold, Germany).
Performing a CBC requires doing a microhematocrit
, a dilution for a WBC on a Coulter D[.
A PCV was obtained for each sample after centrifugation (5 minutes at 10 400 rpm) of a glass microhematocrit
tube (75 mm x 1.
Or I might note, "You haven't completed an optimum packing time on the microhematocrit
Packed cell volume (PCV) was measured manually by using plain capillary microtubes and a microhematocrit
centrifuge (Sigma, Osterode, Germany) at 13 845g for 5 minutes.
