Which type of laboratory testing is primarily performed in hematology?

The complete blood count (CBC) is a fundamental test in hematology, which is the study of blood, blood-forming organs, and the disorders that affect them. The CBC evaluates various components of the blood, including red blood cells, white blood cells, hemoglobin, hematocrit, and platelets. This comprehensive assessment provides crucial information about a person's overall health and helps in diagnosing conditions such as anemia, infections, and leukemia, among others.

In contrast, blood glucose tests primarily measure blood sugar levels and are typically associated with diabetes management rather than hematology. Microbial cultures are used to identify pathogens in samples, which falls under microbiology, not hematology. Urinalysis involves the examination of urine and is used to assess the renal and metabolic status of an individual, again placing it outside the realm of hematological testing. Thus, the complete blood count stands out as the specific test that aligns with the focus of hematology.
