What's this test for?

This test is ideal if you're experiencing persistent skin, nail, or scalp issues like redness, itching, scaling, or thickened nails that won't clear up. It checks for an immune response to Trichophyton rubrum, a common fungus responsible for many stubborn skin and nail infections. It's especially useful if over-the-counter treatments haven't worked and you want to understand what's driving your symptoms.

What happens after I get my results?

Your results will show up in your account with the normal range clearly explained next to your value, so you know exactly where you stand. If your result suggests a past or ongoing exposure to this fungus, next steps might include starting or adjusting an antifungal approach, keeping skin dry and clean, and retesting after treatment to confirm the infection has cleared. You can download a standard lab report straight from your account at any time, and use the trends feature to track how your levels change if you test again in the future. If symptoms are severe or spreading quickly, seek medical care right away.

Who should consider this test?

Anyone with long-lasting or recurring skin, scalp, or nail infections that resemble ringworm, athlete's foot, or jock itch could benefit from this test. It's also useful for people who've tried creams or sprays without success and want more clarity before trying something stronger. Athletes, gym-goers, and people in humid climates who are more prone to fungal exposure may also find this test helpful.

What symptoms indicate I may need this test?

Common signs include itchy, red, ring-shaped patches on the skin, flaking or peeling between toes, thickened or discolored nails, or patchy hair loss on the scalp. If these symptoms keep coming back even after using antifungal products, it may be a sign the infection is more established. Persistent or spreading symptoms are a good reason to check for this specific fungus.

How can I naturally support skin healing from fungal issues?

Keeping skin clean and completely dry, especially between toes and skin folds, helps prevent fungus from spreading. Wearing breathable fabrics, changing socks and underwear daily, and avoiding shared towels or shoes can reduce reinfection risk. Some people find relief using diluted tea tree oil or apple cider vinegar rinses, though these work best alongside proper hygiene, not as a replacement for treatment.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. You'll get a notification once they're posted to your account, where you can view and download the full report.

What does a high result mean?

A high or positive result means your immune system has produced antibodies in response to Trichophyton rubrum, suggesting current or recent exposure to this fungus. This often lines up with visible skin, nail, or scalp symptoms. It's a good idea to start or continue antifungal care and retest later to see if the levels come down.

What causes elevated Trichophyton rubrum IgG levels?

Direct contact with the fungus is the main cause, often through shared surfaces like locker room floors, gym mats, damp shoes, or infected towels. Warm, sweaty environments make the skin more vulnerable, which is why athletes and people in humid climates are more commonly affected. Weakened skin barriers from cuts, excessive moisture, or tight-fitting shoes can also increase the chance of infection.

How often should I retest?

If you're being treated for an active infection, retesting 4-6 weeks after finishing treatment can help confirm it has cleared. If your first test was negative but symptoms persist, retesting in a few weeks may catch an infection that was too early to detect. Otherwise, this isn't a test most people need on a regular basis unless symptoms return.

What should I do if my results are abnormal?

Start with good hygiene habits: keep the affected area clean and dry, avoid scratching, and don't share personal items like towels or shoes. Consider using an antifungal cream, powder, or spray suited to the affected area, and give it several weeks to work. If symptoms don't improve, spread, or worsen, seek medical care to discuss stronger treatment options.
