The anticonvulsant drug, lamotrigine, has been associated with a decrease in white blood cell count. [2] The FDA monograph for metronidazole states that this medication can also cause leukopenia, and the prescriber information suggests a complete blood count, including differential cell count, before and after, in particular, high-dose therapy. [3]
A white blood cell differential is a medical laboratory test that provides information about the types and amounts of white blood cells in a person's blood. The test, which is usually ordered as part of a complete blood count (CBC), measures the amounts of the five normal white blood cell types – neutrophils, lymphocytes, monocytes, eosinophils and basophils – as well as abnormal cell ...
A normal human platelet count ranges from 150,000 to 450,000 platelets/microliter (μL) of blood. [4] Values outside this range do not necessarily indicate disease. One common definition of thrombocytopenia requiring emergency treatment is a platelet count below 50,000/μL. [5]
An excess of white blood cells is usually due to infection or inflammation. Less commonly, a high white blood cell count could indicate certain blood cancers or bone marrow disorders. The number of leukocytes in the blood is often an indicator of disease, and thus the white blood cell count is an important subset of the complete blood count.
A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).
A low level of neutrophils (a specific type of white blood cell) may also be found in some individuals with Waldenström macroglobulinemia. [ 49 ] Chemistry tests include lactate dehydrogenase (LDH) levels, uric acid levels, erythrocyte sedimentation rate (ESR), kidney and liver function, total protein levels, and an albumin-to-globulin ratio.
In adults, absolute lymphocytosis is present when the lymphocyte count is greater than 5000 per microliter (5.0 x 10 9 /L), in older children greater than 7000 per microliter and in infants greater than 9000 per microliter. [1] Lymphocytes normally represent 20% to 40% of circulating white blood cells. When the percentage of lymphocytes exceeds ...
After vascular surgery, 34% of patients receiving heparin developed HIT antibodies without clinical symptoms. [15] The exact number of cases of HIT in the general population is unknown. What is known is that women receiving heparin after a recent surgical procedure, particularly cardiothoracic surgery , have a higher risk, while the risk is ...
