Q. How are allergies diagnosed, and what types of tests are commonly used?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Allergy diagnosis typically involves a combination of medical history assessment, physical examination, and specific allergy tests. Common allergy tests include:
1. Skin Prick Test (SPT):
- This is one of the most common and widely used allergy tests. Small amounts of allergens (such as pollen, dust mites, pet dander) are applied to the skin, usually on the forearm or back. The skin is then pricked with a tiny needle to allow the allergen to enter the skin. If a person is allergic, a small raised bump resembling a mosquito bite will appear at the test site.
2. Blood Tests (Specific IgE Tests):
- Blood tests can measure the levels of specific antibodies (IgE) produced in response to specific allergens. Common blood tests for allergies include the ImmunoCAP test and the RAST (radioallergosorbent test). These tests can be useful when skin testing is not feasible or if a person has a skin condition that may interfere with the results.
3. Patch Test:
- Patch testing is used to diagnose contact dermatitis, a type IV delayed hypersensitivity reaction. Small amounts of potential allergens are applied to patches, which are then affixed to the skin. After a specified period, the patches are removed, and the skin is examined for any signs of an allergic reaction.
4. Elimination Diet:
- In cases of suspected food allergies, an elimination diet may be used. Common allergenic foods are removed from the diet for a certain period, and then they are reintroduced one at a time to identify the specific food triggering the allergic reaction.
5. Challenge Test:
- A challenge test involves exposing a person to a suspected allergen in a controlled environment under medical supervision. This test is often used for diagnosing food allergies.
It's important to note that the interpretation of allergy tests requires expertise from a healthcare professional, typically an allergist or immunologist. These specialists consider the individual's medical history, symptoms, and test results to make an accurate diagnosis. Self-diagnosis based solely on test results or online resources is not recommended.
If you suspect you have allergies, consult with a healthcare professional for proper evaluation and diagnosis. They can recommend appropriate tests and develop a comprehensive plan for managing your allergies.
Q. Hello Doctor, from past 3 weeks I have too much dandruff problem and it cause hair loss will you suggest any best solution for this?

Answered by Secondmedic ExpertDealing with excessive dandruff leading to hair loss can be frustrating, but there are effective ways to address this issue. Here's what you can do:
1. Switch to a Gentle Shampoo: Opt for shampoos specifically designed for dandruff, containing ingredients like ketoconazole, zinc pyrithione, coal tar, or selenium sulfide. Use these shampoos regularly to reduce dandruff buildup.
2. Scalp Massage: Gently massage your scalp while shampooing to help remove flakes and improve blood circulation, which can promote healthier hair growth.
3. Avoid Hot Water: Wash your hair with lukewarm water instead of hot water, as hot water can dry out your scalp and worsen dandruff.
4. Balanced Diet: Ensure you're eating a balanced diet rich in vitamins and minerals essential for healthy hair and scalp, such as omega-3 fatty acids, zinc, and B vitamins.
5. Manage Stress: Stress can exacerbate dandruff problems. Practice stress-relief techniques like meditation, yoga, or regular exercise to help manage stress levels.
6. Apple Cider Vinegar Rinse: Consider using diluted apple cider vinegar as a rinse after shampooing. It can help restore the scalp's pH balance and reduce dandruff.
7. Consult a Dermatologist: If the issue persists despite trying home remedies or over-the-counter solutions, seek advice from a dermatologist. They can provide a personalized treatment plan tailored to your specific scalp condition.
Remember, consistency is key when dealing with dandruff. Give these remedies some time to work, as immediate results might not always occur. It's essential to find what works best for your scalp, so don't get discouraged if you don't see immediate improvements.
Taking care of your scalp health not only addresses dandruff but also aids in reducing hair loss associated with this issue. Feel free to incorporate these tips into your routine and observe how your scalp responds. If the problem persists or worsens, seeking professional guidance is always recommended.
