Understanding Lab Tests for Impaired Immune Response
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
An impaired immune response refers to a weakened ability of the body's immune system to fight off infections, diseases, and other foreign substances. While there is no single blood test that directly diagnoses impaired immunity, lab testing is fundamental for assessing nutritional factors and underlying conditions that may compromise immune function.
Recommended Test
Vitamin E (Tocopherol)
This test measures vitamin E levels in the blood, which plays a crucial role in maintaining a healthy immune system. Low levels of vitamin E, particularly Beta Gamma Tocopherol, can contribute to impaired immune response and increase susceptibility to infections. Monitoring vitamin E status helps identify potential nutritional deficiencies that may be compromising immune function.

Why Blood Testing is Important for Immune Health
The immune system relies on various nutrients, vitamins, and minerals to function optimally. Blood tests can identify deficiencies in key nutrients that support immune function, helping healthcare providers understand potential contributing factors to weakened immunity and guide appropriate interventions.
Understanding Your Results
Vitamin E deficiency may indicate a nutritional factor contributing to weakened immune function. However, immune system health is complex and involves multiple factors including overall nutrition, lifestyle, underlying medical conditions, and genetics. Your healthcare provider can interpret results in the context of your overall health status.
