What Sets the Biome Burden™ Profile Apart
The Biome Burden™ Profileby Cyrex Labs is not just another stool or PCR test—it’s a next-generation immune screening tool. Here’s why it’s different:
Immune Reactivity, Not Just Pathogen Presence
Most conventional tests detect microbes only if they’re actively present in the blood, stool, or tissue. The Biome Burden™ Profile detects your immune system’s memory and current response—uncovering stealth pathogens that may be hiding in tissues, biofilms, or previously activated infections.
Screens for IgG, IgA, and IgM Antibodies
This three-pronged antibody panel provides a comprehensive view of both recent and past immune challenges. Whether your exposure was recent, chronic, or even dormant, this test increases the likelihood of detection.
Covers Over 30 Pathogens Across 4 Microbial Classes
Test includes clinically relevant antigens from:
Bacteria (Borrelia, Mycoplasma, Yersinia, H. pylori, etc.)
Viruses (EBV, CMV, HHV-6)
Fungi/Yeasts (Candida, Aspergillus)
Parasites (Giardia, Toxoplasma, Entamoeba)
Autoimmunity & Molecular Mimicry Focus
Cyrex is known for precision testing that identifies cross-reactivity between microbes and human tissues. This test can reveal microbial triggers involved in molecular mimicry, a leading cause of autoimmune disease.
Ideal for Complex and Sensitized Individuals
This test is especially helpful if you:
Have chronic symptoms with normal labs
React poorly to antimicrobials without a clear cause
Have MCAS, Alpha-Gal, mold illness, Long Covid Symptoms or Lyme-like syndromes
Suspect your immune system is overburdened or misfiring
