The normal Hb level for males is 14 to 18 g/dl that for females is 12 to 16 g/dl. Blood viscosity, erythrocyte deformability, and hematocrits were measured in normal male and female mice, as well as in females and castrated males after short-term (2-weeks) and long-term (5-7 months) testosterone intervention (50 mg/kg, weekly). The amount of hemoglobin in whole blood is expressed in grams per deciliter (g/dl). That is why it is good to start donating when you are in the 51-52 hematocrit range. To ensure adequate tissue oxygenation, a sufficient hemoglobin level must be maintained. Sources include Labcorp, Quest Diagnostics, and Rush University. A low level of hemoglobin or hematocrit is a sign of anemia. Hemoglobin (Hb) is the protein contained in red blood cells that is responsible for delivery of oxygen to the tissues. The normal hematocrit for men is 40 to 54. RBC: total red blood cell count, HCT: hematocrit, Hb: hemoglobin, MCV: mean corpuscular hemoglobin concentration (HCT/HCT×10), MCH: mean corpuscular hemoglobin.

Nonetheless, other investigators have reported that hematocrit less than 40% to 44% had a high predictive value of approximately 90% in excluding severe pancreatitis ( Khan et al, 2002 Lankisch et al, 2001). Following are the normal ranges for common lab tests for adults. The hematocrit measures the volume of red blood cells compared to the total blood volume (red blood cells and plasma). Both albumin and total protein decrease by about 1g/dL by mid-pregnancy and. Important among these are albumin, total protein and creatinine. There are also many changes in blood chemistries during pregnancy as well, mostly by the same dilutional mechanism as the hematocrit.

However, the value of hematocrit remains controversial, because several large studies failed to demonstrate its prognostic value on admission ( Alsfasser et al, 2013). The low normal range is considered to be about 106-120k. Hematocrit greater than 50% has also been shown to predict severe pancreatitis ( Gan et al, 2004). A hematocrit of more than 44% on admission or the absence of a fall in hematocrit during the first 24 hours after admission was found to be a clear risk factor for pancreatic necrosis, organ failure, or pancreatic infection ( Brown et al, 2000). The hematocrit value has been shown to be a prognostic marker for the severity of AP, and its prognostic significance emphasizes the pathophysiologic role of fluid loss in the severity of pancreatitis and the role of vigorous fluid replacement in the course of disease.
