Understanding Lab Tests for Polymyalgia Rheumatica

Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025

Polymyalgia rheumatica is an inflammatory condition that causes muscle pain and stiffness, particularly in the shoulders, neck, and hips. While there is no single blood test that directly diagnoses polymyalgia rheumatica, lab testing plays a fundamental role in detecting inflammation levels that support the diagnosis and help monitor treatment response.

Recommended Test

Inflammation test

This test measures how quickly red blood cells settle in a test tube, which indicates the level of inflammation in the body. In polymyalgia rheumatica, the sedimentation rate (ESR) is typically elevated due to muscle inflammation, making it a valuable supporting tool for diagnosis and monitoring treatment effectiveness.

The Role of Blood Testing in Polymyalgia Rheumatica

Diagnosis of polymyalgia rheumatica is primarily based on clinical symptoms and physical examination. However, blood tests are essential for measuring inflammatory markers in the body, which are characteristically elevated in this condition. These tests help healthcare providers confirm their clinical suspicions and rule out other inflammatory conditions.

Understanding Your Results

An elevated ESR supports the diagnosis of polymyalgia rheumatica when combined with characteristic symptoms. This test is also useful for monitoring how well treatment is working, as inflammation markers typically decrease as symptoms improve with appropriate therapy.
