Understanding Lab Tests for Infection or Inflammatory Disease
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Infections and inflammatory diseases encompass a broad range of conditions where the body's immune system responds to pathogens, toxins, or attacks healthy tissues. While specific symptoms and physical examination provide important clues, blood tests are fundamental for confirming the presence of infection or inflammation and determining the appropriate treatment approach.
Recommended Test
Post COVID-19 Expanded Panel
This comprehensive panel includes measurements of various immune system markers, including monocyte levels. Elevated monocytes can indicate ongoing infection or inflammatory conditions such as rheumatoid arthritis or systemic lupus erythematosus. This expanded testing approach provides valuable insights into the body's inflammatory status and helps healthcare providers assess overall immune system function following infection.

The Role of Blood Testing in Diagnosis
Blood tests play a crucial role in detecting infections and inflammatory diseases by measuring specific markers that indicate immune system activity. These tests can reveal elevated white blood cell counts, inflammatory proteins, and other cellular changes that occur when the body is fighting an infection or experiencing inflammation.
Comprehensive Testing for Post-Infectious Monitoring
Following certain infections, comprehensive blood panels can help assess ongoing inflammatory responses and monitor recovery. These expanded panels are particularly valuable for detecting persistent immune system activation that may require ongoing medical attention.
Understanding Your Results
Abnormal results on infection and inflammatory disease panels may indicate active infection, autoimmune conditions, or other inflammatory processes. Your healthcare provider will interpret these results in the context of your symptoms and medical history to determine the most appropriate treatment plan.
