Nearly 15 million units of packed red blood cells and whole blood are transfused annually in the United States alone. Until recently, the major risks from blood transfusion were thought to be transmission of viral infections, and overall, blood transfusion was believed by most providers to be safe.

Acoustofluidic hematocrit determination
Analytica Chimica Acta, 2018Hematocrit (HCT) measurements of blood from patients, blood donors and athletes are routinely performed on a daily basis. These measurements are often performed in centralized hospital labs by whole blood analyzers, which leads to long time-to-result.

Stress is believed to increase hematocrit. Groups of patients with generalized anxiety disorders and normal volunteers matched on age and sex were compared on resting levels of state anxiety, trait anxiety, depression, pulse rate, blood pressure and hematocrit.

The hematocrit (Hct) determines the oxygen carrying capacity of blood, but also increases blood viscosity and thus flow resistance. From this dual role the concept of an optimum Hct for tissue oxygenation has been derived. Viscometric studies using the ratio Hct/blood viscosity at high shear rate showed an optimum Hct of 50–60% for red blood cell (RBC)

Diabetes, 1996
There is limited evidence that raised hematocrit levels may be associated with insulin resistance, which links cardiovascular disease with NIDDM. The association between hematocrit level at screening and the subsequent development of physician-diagnosed NIDDM during 12.8 years of follow-up was examined in a prospective study of 7,735 middle-aged men ...

Hematocrit measurement by dielectric spectroscopy
Proceedings of the Second Joint 24th Annual Conference and the Annual Fall Meeting of the Biomedical Engineering Society] [Engineering in Medicine and Biology, 2002Based on permittivity changes, a new method to measure hematocrit (HCT) in extracorporeal blood systems is presented. Human blood samples were tested at different HCT levels pairing the values of permittivity change, obtained by means of a commercial impedance analyzer, with traditional centrifugation measurements.

WHOLE BODY HEMATOCRIT: LARGE VESSEL HEMATOCRIT RATIO IN HYPERTENSION
Acta Medica Scandinavica, 1968AbstractWhole body hematocrit/large vessel hematocrit (WBH/LVH ratio) has been examined in 21 normotensive and 35 hypertensive subjects and found to be the same, presumably as an expression of a uniform distribution of the blood volume in the two groups.

Optimal hematocrit for hemodialysis
Current Opinion in Nephrology and Hypertension, 1997Considerable controversy continues over the optimal hematocrit target for dialysis patients being treated with recombinant erythropoietin. Recent short-term studies have demonstrated a significant improvement in brain function when hematocrit is 42% compared with when it is 31%.

The Condor, 1980
perimental and control adults fed similar proportions of fish, garbage and intertidal food to their young. Although the young of experimental adults gained weight normally, the adults may have lost more weight than control adults and so lessened their own chances of survival. This possibility could not be investigated.

Microcirculatory hematocrit and blood flow
Journal of Theoretical Biology, 1988Direct measurements from many laboratories indicate that the oxygen tension in skeletal muscle is significantly less than in the large veins draining these tissues. Harris (1986) has proposed that because of the parallel anatomic arrangement of large arterioles and venules in skeletal muscle, a counter-current exchange between these vessels can occur ...
