The total amount of blood in humans varies with age, sex, weight, body type, and other factors, but a rough average figure for adults is about 60 millilitres per kilogram of body weight. An average young male has a plasma volume of about 35 millilitres and a red cell volume of about...
of iron per day to calves that were moderately anemic caused an increase in the number of their red blood cells and hemoglobin levels and thus prevented a further decrease, which normally would have been expected. Iron alone or iron in combination with the copper, cobalt, and manganese cured ...
and the lowest safe limit of hemoglobin for infants less than 2 months of age has not been determined, although in sick infants it is desirable to maintain a hemoglobin level of 12 to 13 g/dL or a hematocrit of 40% (equivalent to 8 g/dL in adults) (seeChapter 14, Blood Conservation...
The most common reasons for low MCH levels are: Anemia.This happens when your body doesn't have enough healthy red blood cells to carry oxygen around your body. The most common cause is low levels of the mineral iron. It's also caused by low levels ofvitamin B12and folate. Hemoglobinopat...
A national survey was conducted in 1969-1972 to determine the range of carboxyhemoglobin levels in various segments of the American population. Venous blood samples for COHb analysis were obtained from 29,000 blood donors living in urban, suburban, and rural communities in the U. S. For compara...
To determine the prevalence of carboxyhemoglobin levels in banked blood exceeding Air Quality Standards (level of carboxyhemoglobin >1.5 percent), we analyzed banked blood for the level of carboxyhemoglobin from 101 randomly selected samples. Of 101 units of banked blood, 49 (49 percent) had carbo...
Recent research found that risk of death is increased in patients with anemia which is dialysis related when levels of hemoglobin are persistently low during several months.
Hemoglobin A1c (HbA1c) examination is the gold standard for diagnosing and monitoring diabetes mellitus patients. In the examination, the pre-analytical phase has the most considerable error rate at 61%. One of the contributing factors is the use of anticoagulants that do not adhere to established...

According to the Centers for Disease Control and Prevention (CDC), the average concentration of blood Pb among healthy unexposed adults was estimated at 0.9 ug/dL. The estimated reference values of permissible Pb blood levels are < 5ug/dL in adults and < 3.5 ug/dL in children, while ...
