What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your biotin levels mean for your hair, skin, nail health, and energy levels. These notes include personalized recommendations like dietary changes to include more biotin-rich foods, supplement suggestions if needed, or whether you should investigate absorption issues. You'll also get the standard lab report and can track your biotin levels over time using our trends feature to see how your dietary changes or supplements are working.

When will I get my results?

Your biotin test results will be available in approximately 14-21 business days after your sample is collected. You'll receive an email notification when your results are ready to view online, along with easy-to-understand doctor notes explaining what your levels mean and any recommended next steps.

Who should consider getting this test?

This test is particularly useful for people experiencing hair loss or thinning that doesn't have an obvious cause, those with persistent fatigue despite adequate sleep, or anyone with skin issues like dermatitis or rashes. It's also important for people taking certain medications (like anti-seizure drugs), those with digestive disorders that affect nutrient absorption, pregnant or breastfeeding women, and anyone following restrictive diets that might limit biotin intake.

What symptoms indicate I may need this test?

Common symptoms of low biotin include noticeable hair thinning or loss, brittle or splitting nails, red scaly rash around the eyes, nose, or mouth, persistent tiredness or low energy, and tingling sensations in the arms or legs. You might also experience muscle aches, mood changes like depression or irritability, and conjunctivitis or eye inflammation. If you're experiencing several of these symptoms together, especially with recent dietary changes or new medications, testing your biotin levels can help identify the cause.

How can I naturally support my biotin levels?

Increasing your intake of biotin-rich foods is the best natural approach. Excellent sources include egg yolks, organ meats like liver, nuts and seeds (especially almonds, peanuts, and sunflower seeds), salmon and other fish, dairy products, and whole grains. Sweet potatoes, spinach, and broccoli are also good sources. Cooking egg whites can actually reduce biotin absorption, so consider soft-boiled eggs. If you have digestive issues, addressing gut health may improve biotin absorption.

What is biotin and why does it matter?

Biotin, also known as Vitamin B7 or Vitamin H, is a water-soluble vitamin that acts as a helper molecule in your body's energy production processes. It plays essential roles in breaking down fats, carbohydrates, and proteins from food into usable energy, supports healthy hair growth and skin cell renewal, and helps maintain proper nervous system function. Because your body doesn't store biotin long-term, you need a regular dietary supply to maintain optimal levels for energy, appearance, and overall health.

What does low biotin mean?

Low biotin levels indicate your body doesn't have enough of this vitamin to properly support hair growth, skin health, and energy metabolism. This can result from inadequate dietary intake, digestive conditions that impair absorption (like Crohn's disease), long-term antibiotic use that disrupts gut bacteria, pregnancy, or genetic disorders affecting biotin metabolism. Low levels can lead to hair thinning, skin problems, fatigue, and neurological symptoms, but these issues typically improve once biotin levels are restored through diet or supplementation.

How often should I retest my biotin levels?

If your initial results show low biotin and you start supplementation or dietary changes, retesting in 8-12 weeks helps confirm your levels are improving. Once your biotin levels are in the optimal range and symptoms have resolved, annual testing is usually sufficient unless symptoms return. If you have ongoing digestive issues, take medications that affect biotin absorption, or are pregnant, your healthcare provider may recommend more frequent monitoring every 3-6 months.
