Blood tests are an essential part of modern medical diagnostics and can provide valuable insights into your overall health. They help doctors identify a variety of health problems, from vitamin deficiencies to serious infections and chronic diseases.

A typical blood test may include a complete blood count (CBC), which measures the number of blood cells, including red and white blood cells, as well as platelets. Biochemistry tests assess various substances in the blood, including minerals, proteins, and enzymes, which can indicate conditions such as kidney or liver disease.
