Understanding Lab Tests for Temporal Arteritis
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Temporal arteritis, also known as giant cell arteritis, is an inflammatory condition affecting the arteries in the temple area and other parts of the body. While there is no single blood test that directly diagnoses temporal arteritis, laboratory testing plays a fundamental role in detecting inflammation markers that support the diagnosis and help monitor treatment response.
Recommended Test
Inflammation test
This test measures the erythrocyte sedimentation rate (ESR), which indicates the level of inflammation in the body. In temporal arteritis, the ESR is frequently elevated, making it a valuable marker for supporting diagnosis and monitoring disease activity. An increased sedimentation rate reflects the inflammatory process affecting the arteries.

The Role of Blood Testing in Temporal Arteritis
Temporal arteritis is primarily diagnosed through clinical evaluation and imaging studies, but blood tests are essential for measuring inflammation levels in the body. These inflammatory markers help healthcare providers assess disease activity and guide treatment decisions, making laboratory testing a critical component of comprehensive care.
Understanding Your Results
An elevated ESR suggests the presence of inflammation but is not specific to temporal arteritis alone. Your healthcare provider will interpret these results alongside your symptoms, physical examination, and other diagnostic tests to make an accurate diagnosis and develop an appropriate treatment plan.
