White blood cell count normal range

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-... 

Leukocytosis Elevation of the white blood cell count above the normal range. 

The patient was profoundly leukopenic with a white blood cell count of 700/pL-28% polymorphonuclear leukocytes (PMN s), 53% band forms, 3% metamyelocytes, 11% lymphocytes, 5% monocytes. [Normally, the total white blood cell count should be between about 4000 and 10,000 per mL.] The serum creatinine was 3.6 mg/dL (indicating significant renal dysfunction, normal creatinine ordinarily should not exceed about 1 mg/dL). A random plasma vancomycin level was 48.8 pg/mL. (Therapeutic range for peak level is 18 to 30 pg/mL.)... 

Culture and sensitivity White blood cell count At initiation of treatment 1 time/week until within normal range ... 

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). 

The white blood cell count is within the normal range of 4500/mm to 10,000/mm. 

Laboratory abnormalities of routine tests most commonly involve tests of liver function, and patients with acute Q fever may present with a clinical picture of acute hepatitis. Depending on the locale, reported elevations of aspartate aminotransferase, alanine transferase, or both, in the range of 2- to 3-fold higher than the upper limit of normal, are observed in 50% to 75% of patients, while elevation of the alkaline phosphatase is observed in 10% to 15% of patients. The total bilirubin can be expected to be elevated in 10% to 15% of patients with acute Q fever. The white blood cell count is usually normal the erythrocyte sedimentation rate is elevated in one third of patients.65 Mild anemia or thrombocytopenia may also be observed. 

In a small open trial 79 patients with active duodenal ulceration were treated with a 6-week course of cimetidine in doses of 1.6 g daily (13 ). No statistically significant change in the haemoglobin, white blood cell count or serum enzymes (SCOT, alkaline phosphatase etc.) was associated with treatment. Plasma creatinine showed a significant increase during use but the mean level remained within the normal range. In one patient the drug was stopped 2 days before the end of the 6-week course because a maculo-papular rash had developed over the forehead. 

Most infections result in elevated white blood cell (WBC) counts (leukocytosis) because of the mobilization of granulocytes and/or lymphocytes to destroy invading microbes. The generally accepted range of normal values for WBC counts is between 4,000 and 10,000/mm3. 

Patients receiving IFN experience side effects similar to influenza symptoms headache, nausea and tiredness. IFN also decreases red blood cells, white blood cells and platelet counts. A measure of the effectiveness of IFN treatment is the marker called alanine aminotransferase in blood. The normal range is 10-70 U/L. 

Red cell, white cell, platelet counts, white blood cell differential, hematacrit and red cell indices must be performed by an accredited laboratory. The normal ranges for the red cell and white cell counts are influenced by altitude, race, and sex, and therefore should be determined by the acaedited laboratory in the specific area where the tests are performed. 

Laboratory tests showed that hemoglobin was 7.5 g/dL (normal range is 12-15 g/dL), and the reticulocyte count was 262 x 109/L (normal range is 50-100 X 109/L). The tests also indicated neutrophilia, a white cell count of 34 X 109/L (normal range is 4-11 x 109/L), and a platelet count of 328 X 109/L (normal range is 150-400 X 109/L). Renal function was normal. Malarial parasite screen and direct Coombs test were negative. Blood film showed nucleated red blood cells and anisocytosis with bite cells ...
