5 Signs That a Complete Blood Count Can Show You

Anemia

Low red blood cells or hemoglobin often point to anemia, leaving you tired, pale, and short of breath even after simple tasks.

Infection

Changes in white blood cell (WBC) levels can occur during infections. However, WBC counts can also be affected by inflammation, stress, medications, and other health conditions.

Inflammation

Changes in WBC levels can sometimes occur with inflammation. Your doctor may interpret these findings along with your symptoms and other test results.

Nutritional Deficiencies

Changes in red blood cell size and other indices can provide clues to iron, vitamin B12, or folate deficiency. Your doctor may recommend additional tests to confirm the cause.

Blood Disorders

Changes in red cells, white cells, or platelets may indicate specific blood disorders requiring further investigation.
