Answer:
By counting the blood cells i.e RBC , WBC, and platelets. Also by the microscopic observation of blood smears to observe the variation in cell size and shape or overall appearance.
Explanation:
In the diseased condition the number of blood cells may vary in their count. Usually in a healthy individual the number of RBCs are 4.5 to 5.5 million cells/mm3, the number of WBCs are 5,000 to 10,000 cells/mm3 and the number of platelets are 140,000 to 400,000/mm3. Any deviation from this count indicated diseased condition. Sometimes the shape of RBC may vary like in sickle cell anemia, so by microscopic observation we can check for blood cell appearance.
There are different blood tests to find out the disease of the blood.
The tests are:
Blood diseases are diseases that affect blood cells in the body.
Blood diseases are anemia, Leukocytosis, Thalassemia, Hemophilia, Von Willebrand disease, etc.

This test is the most commonly used test. CBC can detect many blood diseases and disorders such as anemia, blood clotting, blood cancer, etc.
Lipoprotein panel test:
This test is called the lipoprotein panel test. This test helps in detecting coronary heart diseases.
Blood chemistry tests:
The basis metabolic panel test (BMP) detects different chemicals level in the blood. Such as glucose level, level of calcium, and in kidneys level of blood urea nitrogen.
Blood enzyme tests:
There are various enzymes present in the blood, to carry out biological reactions. This test is used to detect a heart attack.
