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).
There are several ways to measure glycated hemoglobin, of which HbA1c (or simply A1c) is a standard single test. [5] HbA1c is measured primarily to determine the three-month average blood sugar level and is used as a standard diagnostic test for evaluating the risk of complications of diabetes and as an assessment of glycemic control .
Iron is an essential part of hemoglobin, and low iron levels result in decreased incorporation of hemoglobin into red blood cells. In the United States, 12% of all women of childbearing age have iron deficiency, compared with only 2% of adult men. The incidence is as high as 20% among African American and Mexican American women. [75]
Hemoglobin A2 (HbA 2) is a normal variant of hemoglobin A that consists of two alpha and two delta chains (α 2 δ 2) and is found at low levels in normal human blood.Hemoglobin A2 may be increased in beta thalassemia or in people who are heterozygous for the beta thalassemia gene.
A solubility test relies on the fact that HbS is less soluble than normal hemoglobin (HbA); it is highly reliable but does not distinguish between full SCD and carrier status. [83] Tests which can be used for SCD as well as for other hemoglobinopathies: Hemoglobin electrophoresis is a test that can detect different types of hemoglobin ...
Since the average platelet size is larger when the body is producing increased numbers of platelets, the MPV test results can be used to make inferences about platelet production in bone marrow or platelet destruction problems. [1] An increased mean platelet volume (MPV) increases the risk to suffer a heart disease [2]

Because the test pad reaction is dependent on pH, false positive results can occur if the urine is highly alkaline. [ 60 ] [ 62 ] Conventional test strips are not sensitive enough to reliably detect microalbuminuria , a condition in which urine albumin levels are slightly elevated, [ 64 ] although dipsticks specialized for this measurement exist.
