The hematocrit (/ h ɪ ˈ m æ t ə k r ɪ t /) (Ht or HCT), also known by several other names, is the volume percentage (vol%) of red blood cells (RBCs) in blood, [1] [2] measured as part of a blood test. [3] The measurement depends on the number and size of red blood cells. [3] It is normally 40.7–50.3% for males and 36.1–44.3% for ...
Mean corpuscular volume (MCV) is the average volume of a red blood cell and is calculated by dividing the hematocrit (Hct) by the concentration of red blood cell count. [citation needed] = [] Normal range: 80–100 fL (femtoliter)
Red blood cell concentrates, also known as red cell concentrates or packed red blood cells, are red blood cells that have been separated for blood transfusion. [1] A red blood cell concentrate typically has a haematocrit of 0.50 – 0.70 L/L and a volume between 250 and 320 mL.
The RDW is a statistical calculation made by automated analyzers that reflects the variability in size and shape of the RBCs. ... if the Hct = 42.5% and [RBC] = 4.58 ...
The Mentzer index, described in 1973 by William C. Mentzer, [1] is the MCV divided by the RBC count. It is said to be helpful in differentiating iron deficiency anemia from beta thalassemia trait.
- Second trimester hemoglobin < 10.5 g/dL - Third trimester hemoglobin < 11 g/dL - Postpartum hemoglobin < 10 g/dL Listed below are normal ranges for important lab values in the diagnosis of anemia. Keep in mind that these ranges might change based on each patient's stage in pregnancy: [7] - Hemoglobin: Men (13.6-16.9), women (11.9-14.8)
The microhematocrit data along with the I-131 indicator data provide a normalized hematocrit number, more accurate than hematocrit or peripheral hematocrit measurements. [9] Measurements are taken 5 times at 6-minute intervals so that the BVA-100 can calculate the albumin transudation time to understand the flux of liquid through capillary ...
Polycythemia is defined as serum hematocrit (Hct) or hemoglobin (HgB) exceeding normal ranges expected for age and sex, typically Hct >49% in healthy adult men and >48% in women, or HgB >16.5 g/dL in men or >16.0 g/dL in women. [8] The definition is different for neonates and varies by age in children. [9] [10]
