Blood Test (Biochemistry and Hematology)
Blood tests are commonly used medical procedures that involve collecting a blood sample to analyze various components of the blood, such as chemicals, cells, and proteins. They provide essential information about a person’s health and help diagnose, monitor, and treat medical conditions.

A blood test is a medical procedure that involves collecting a sample of blood from a patient in order to analyze it for various purposes. The two main categories of blood tests are biochemistry and hematology.
Biochemistry blood test, also known as blood chemistry tests or blood panels, analyze the chemical components of the blood to assess the functioning of various organs and systems in the body. These tests provide valuable information about the levels of different substances present in the blood, such as electrolytes, enzymes, hormones, proteins, fats, and sugars. They can help diagnose and monitor conditions like diabetes, kidney or liver function test biochemistry, nutritional deficiencies, hormonal imbalances, and more.
Hematology blood test, on the other hand, focus on the cellular components of the blood, including red blood cells, white blood cells, and platelets. These tests provide information about the quantity, quality, and characteristics of these blood cells. Common hematology test includes the complete blood count (CBC), which measures the levels of red and white blood cells, hemoglobin, hematocrit, and platelets. The hematology CBC test can help diagnose conditions like anemia, infections, blood clotting disorders, and certain types of cancers.
During a blood test, a healthcare professional typically collects a small sample of blood from a vein in the arm using a needle and a syringe or through a process called venipuncture. The blood sample is then sent to a laboratory for analysis, and the results are usually interpreted by a medical professional for biochemical analysis of blood.
It’s important to note that the specific tests included in a blood test can vary depending on the purpose of the test and the patient’s medical history.
