There are various kinds of laboratory tests, which are intended to analyze different types of samples. The most common types of laboratory tests include:   • Clinical chemistry testing - This type of lab testing involves looking for chemical markers in the blood, urine, and other bodily fluids that may point to diseases or imbalances. Clinical chemistry tests assess blood glucose levels, liver and kidney function, electrolyte levels, and more. • Microbiology - Microbiology testing involves looking for the presence of bacteria, viruses, fungi, or parasites in samples of blood, urine, or other bodily fluids. • Hematology - Blood cells, such as red blood cells, white blood cells, and platelets, are examined using hematology testing. Anemia, blood cancers, and other blood disorders can all be diagnosed with this type of lab testing. • Immunology - Immunology tests assess the blood's concentrations of antibodies, proteins, and other immune system elements. It is useful in the diagnosis of infections, allergies, and autoimmune diseases. • Toxicology - Toxicology testing looks for the presence of drugs, alcohol, or other toxic substances in the blood, urine, or hair samples. • Histology - To detect abnormalities or diseases, such as cancer, histology testing involves examining tissue samples under a microscope.
