Leaky gut syndrome is a condition where the intestinal lining becomes compromised, allowing undigested food particles and bacteria to pass into the bloodstream. It is caused by increased intestinal permeability that triggers immune responses to food proteins that cross the damaged gut barrier. The Red Kidney Bean IgG test is the most important test for detecting immune reactions associated with leaky gut syndrome.

Leaky gut syndrome is caused by damage to the tight junctions between intestinal cells that normally form a protective barrier. When these connections weaken, the intestinal lining becomes more permeable, allowing larger food particles, bacteria, and toxins to pass through into the bloodstream. This breach triggers immune responses and inflammation throughout the body. Common factors that damage the gut lining include chronic stress, excessive alcohol consumption, long-term use of NSAIDs, infections, and inflammatory bowel conditions.
The Red Kidney Bean IgG test is the most important blood test for leaky gut syndrome because it detects elevated IgG antibodies specific to kidney bean proteins in your bloodstream. When your gut lining is compromised, undigested food particles like kidney bean proteins can cross the intestinal barrier and trigger your immune system to produce food-specific IgG antibodies. Elevated levels indicate that food proteins are entering your bloodstream and causing immune reactions, which is a hallmark of increased intestinal permeability. This test provides concrete evidence of immune responses that may be associated with leaky gut syndrome and helps guide dietary interventions.
You should get tested if you experience persistent digestive issues like bloating, gas, diarrhea, or constipation that do not improve with standard treatments. Other signs include unexplained food sensitivities, chronic fatigue, joint pain, skin problems like eczema or acne, frequent infections, or autoimmune conditions. Testing is especially important if you notice symptoms worsening after meals or if you have a history of inflammatory bowel disease, celiac disease, or prolonged NSAID use. Early detection allows you to make targeted dietary and lifestyle changes before complications develop.

What this means
Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
Recommended actions
Increase resistance or strength training
Prioritize 7–8 hours of quality sleep per night, try to reduce stress
Include more zinc- and magnesium-rich foods (like shellfish, beef, pumpkin seeds, spinach)
Consider retesting in 3–6 months
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
