Understanding Lab Tests for Severe Bacterial Infections
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Severe bacterial infections are serious medical conditions that require prompt diagnosis and treatment. While diagnosis typically involves identifying the specific bacteria through cultures and clinical assessment, blood tests play a crucial role in monitoring the body's immune response and guiding treatment decisions.
Recommended Test
Lysozyme
This test measures lysozyme levels in the blood, an enzyme that helps destroy bacterial cell walls. During severe bacterial infections, lysozyme levels typically increase as the body's immune system actively fights the infection, making it a valuable marker for assessing immune response and infection severity.

The Role of Blood Testing in Bacterial Infections
When the body fights a severe bacterial infection, various immune markers and proteins in the blood change in response to the infection. Blood tests are fundamental for assessing the intensity of the immune response, monitoring treatment effectiveness, and detecting potential complications.
Understanding Your Results
Elevated lysozyme levels may indicate that your immune system is actively responding to a bacterial infection. However, results must be interpreted alongside clinical symptoms and other diagnostic findings by a healthcare professional to ensure appropriate treatment.
