Understanding Lab Tests for Testicular Cancer
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Testicular cancer is primarily diagnosed through physical examination and imaging studies. While there is no single blood test that can definitively diagnose testicular cancer, certain blood tests play a crucial role in detecting tumor markers, monitoring treatment response, and assessing hormonal changes associated with this condition.
Top Recommended Test
Alpha-Fetoprotein (AFP), Serum, Tumor Marker
AFP is an important tumor marker that is often elevated in certain types of testicular cancer, particularly non-seminomas. This test is valuable for both initial assessment and ongoing monitoring of the disease, helping to track treatment response and detect potential recurrence.

The Role of Blood Testing in Testicular Cancer
Blood tests are fundamental for measuring specific proteins and hormones that can be elevated in testicular cancer. These tumor markers help healthcare providers assess the extent of the disease, monitor treatment effectiveness, and detect potential recurrence. Additionally, testicular cancer can affect hormone production, making hormonal testing an important component of overall health assessment.
Other Relevant Tests
Testosterone, Free, Bioavailable and Total, LC/MS/MS
Testicular cancer can affect hormone production, sometimes causing changes in testosterone levels. This comprehensive test measures different forms of testosterone to assess hormonal status and monitor how the cancer may be impacting normal testicular function.

Understanding Tumor Markers
Tumor markers like AFP are proteins produced by cancer cells or by the body in response to cancer. While elevated levels can indicate the presence of certain types of testicular cancer, it's important to note that not all testicular cancers produce these markers, and elevated levels can sometimes occur in other conditions as well.
Important Considerations

Blood tests for testicular cancer should always be interpreted by a healthcare provider in conjunction with physical examination and imaging studies. Always consult with a healthcare provider for proper diagnosis and treatment.
