Latex allergy is an immune system reaction to proteins found in natural rubber latex from the Hevea brasiliensis rubber tree. It is caused by the immune system producing IgG and IgE antibodies against latex proteins, leading to allergic responses upon contact with latex products. The Allergen Specific IgG Latex (H. brasiliensis) test is the most important test for diagnosing latex allergy and confirming immune system sensitization.

Latex allergy is caused by an immune system reaction to proteins found in natural rubber latex derived from the Hevea brasiliensis rubber tree. When you come into contact with latex products like medical gloves, balloons, or rubber bands, your immune system mistakenly identifies these harmless latex proteins as dangerous invaders and produces antibodies (IgG and IgE) to fight them. Repeated exposure to latex over time increases sensitization, which is why healthcare workers, people who have had multiple surgeries, and those with frequent medical procedures are at higher risk of developing this allergy.
The Allergen Specific IgG Latex (H. brasiliensis) test is the most important blood test for latex allergy because it detects specific IgG antibodies your immune system produces in response to latex proteins from the rubber tree. This test provides definitive confirmation that your body has mounted an allergic response to latex exposure, which is essential for distinguishing true latex allergy from irritant contact dermatitis or other skin conditions. By measuring the level of latex-specific antibodies in your blood, this test helps your healthcare provider assess the severity of your allergic response and develop an appropriate treatment and avoidance plan, especially important for people working in healthcare or other high-exposure environments.
You should get tested if you experience skin reactions like itching, redness, or hives after wearing latex gloves or touching rubber products, develop respiratory symptoms such as sneezing, runny nose, or difficulty breathing when around latex, or have experienced unexplained allergic reactions during medical or dental procedures. Testing is especially important if you work in healthcare, have undergone multiple surgeries, have a history of other allergies (particularly to foods like bananas, avocados, or kiwi), or have had progressively worsening symptoms with latex exposure. Early diagnosis allows you to implement proper avoidance strategies and prevent potentially life-threatening anaphylactic reactions.

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
