Understanding Lab Tests for Sickle Cell Anemia
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Sickle cell anemia is a genetic blood disorder that affects the shape and function of red blood cells. In this condition, abnormal hemoglobin causes red blood cells to become rigid and sickle-shaped, leading to various complications. Blood testing is essential for both diagnosing this condition and monitoring its effects on the body.
Top Recommended Test
Sickle Cell Test
This is the primary diagnostic test for sickle cell anemia. It screens for the presence of abnormal sickle cell hemoglobin (hemoglobin S). A positive result indicates the presence of sickle cell hemoglobin and confirms the diagnosis of this genetic blood disorder.

Diagnosing Sickle Cell Anemia
Sickle cell anemia is caused by a genetic mutation that produces abnormal hemoglobin (hemoglobin S). Specialized blood tests can detect the presence of this abnormal hemoglobin, providing a definitive diagnosis. Early detection is crucial for proper management and treatment planning.
Monitoring Disease Complications
Beyond diagnosis, blood testing plays a vital role in monitoring the complications associated with sickle cell anemia. The rigid, sickle-shaped cells can cause blockages in blood vessels and affect blood flow, making regular monitoring essential for comprehensive care.
Other Relevant Tests
Viscosity, Serum
This test measures how thick the blood serum is. In sickle cell anemia, the rigid, sickle-shaped red blood cells can stick together and increase serum viscosity, which affects blood flow. Monitoring viscosity helps assess the severity of blood flow complications.

Importance of Regular Testing
For individuals with sickle cell anemia, regular blood testing is crucial for monitoring disease progression, assessing the effectiveness of treatments, and detecting complications early. These tests help healthcare providers make informed decisions about care and treatment adjustments.
