Hematocrit normal range

Hematological Effects. A report on 5 individuals (3 males, 2 females) who intentionally ingested 60-180 mb of 25% diazinon solution (estimated to deliver a dose of 240-400 mg/kg for males and 509-986 mg/kg for females) found that leucocyte counts (3,700, 95% polymorphonuclear), hemoglobin (16.3 g), and hematocrit (47) were all within normal ranges (Klemmer et al. 1978). 

No adverse hematological changes were observed in rats that were exposed to 24.4 or 174 mg/m of octaBDE dust for 8 hours/day for 14 consecutive days (IRDC 1978). Evaluation of hemoglobin, hematocrit, total erythrocyte count, and total and differential leukocyte counts showed no remarkable responses except for an elevation in leukocyte numbers. The observed increase in leukocyte counts was considered to be an unusual response by tlic investigators, although it was within the normal range for control rats in their laboratory. 

The use of testosterone replacement therapy for the treatment of hypogonadism and ED may assist PDE5 inhibitors if they have failed to be effective (57). Testosterone levels within the normal range have neutral or potentially beneficial effects on the cardiovascular system (58). Androgen replacement therapy should be offered to men with CAD and hypogonadism if symptomatically appropriate. The absence of long-term studies needs to be addressed in terms of possible preventive properties on the vascular wall, reduction in low-density lipoprotein levels, and the reduction of insulin resistance in contrast to the increase in hematocrit and risk of exacerbating prostate cancer. 

Blood tests were performed and had the following results hematocrit 33% (normal is 38%-45%) reticulocyte count 2.0% (normal is 0.5%-1.5%) mean corpuscular volume 90 (normal). A decreased erythrocyte sedimentation rate and a prothombrin time (PT) of 15 s (normal 11-13 s) were noted. A complete blood cell count values for total protein and albumin, ALT, and AST, fasting glucose, Hb-Alc, as well as amylase and lipase were within normal range. Plasma levels of vitamins A and K were below normal, and there was near absence of vitamin E. Dysmorphic red blood cells (RBC) with multiple thorny projections (acanthocytes) were present on a blood smear. All other laboratory tests and findings were within normal limits. 

Blood samples at the end of treatment revealed no significant net change in red blood cell counts, white blood cell counts, platelets, or hematocrit. The concentrations of albumin, uric acid, bilirubin, and liver enzymes remained within the normal range. Plasma free hemoglobin levels were less than 0.2 g/dL. The level of high-density lipoproteins showed no significant change with treatment (58). 

Hematocrit levels also can indirectly indicate fluid volume in the blood. Since the test measures the number of blood cells per volume of blood, increased fluid in the blood, that is, hypervolemia, will dilute the blood cells and cause the hematocrit level to decrease. The normal range of values for men is 39 to 49 percent and for women is 35 to 45 percent. Consequently, too little fluid in the blood, that is, hypovolemia, will cause hemoconcentration and result in a high hematocrit level. It is therefore important to consider the patient s hydration level when interpreting laboratory values. For example, a hematocrit that falls within range or above range in a patient who is dehydrated actually may be low when the patient is fully hydrated. 2 Use other laboratory values, such as specific gravity, to see a full picture. 

As stated in chapter 3, laboratory values often will reveal an elevated hematocrit, high specific gravity, and increased osmolarity. Initially, the blood pressure may remain within normal range or even may be slightly elevated owing to compensatory vasoconstriction, but as compensatory mechanisms fail, blood pressure will decrease. If blood pressure drops below a certain level, the hydrostatic pressure... 

An MRL of 6 ppm has been derived for acute-duration inhalation exposure (14 days or less) to 2-butoxyethanol, based on a NOAEL of 50 ppm for hematotoxicity in pregnant rats (Tyl et al. 1984). An MRL of 3 ppm has been derived for intermediate-duration inhalation exposure to 2-butoxyethanol, based on a NOAEL of 25 ppm for hematotoxicity in rats (Dodd et al. 1983). An MRL of 0.2 ppm has been derived for chronic inhalation exposure (365 days or longer) to 2-butoxyethanol, based on a NOAEL in humans for statistically significant decreased hematocrit and increased mean corpuscular hemoglobin concentrations (Haufroid et al. 1992). The observed changes were still within the range of normal human variability. 

Patients usually do not have abnormalities in the hematocrit, hemoglobin, or platelet levels. The peripheral white blood cell count may range between 5,000 and 22,000 cells per microliter, but it is usually only mildly elevated. Differential blood cell counts are usually normal, although patients may have a lymphocytosis late in the disease.13 67 Patients may have microscopic pyuria, which may lead to the erroneous diagnosis of a urinary tract infection.13,68 Mild elevations in lactic dehydrogenase, serum transaminases, and alkaline phosphatase are commonly seen. Some patients may experience rhabdomyolysis associated with elevations in the serum creatine kinase and urinary myoglobin lev-...
