Which allergy test is better, skin or blood?
Both blood and skin tests may be suggested by our allergy doctor to determine what allergens are triggering your allergic reaction. They are both effective methods of diagnosing food and environmental sensitivities; however, there are some key differences to be aware of.   Because skin tests are more sensitive than blood tests, they are more likely to detect allergies. In addition, skin testing also allows physicians to test a wider range of allergens, which often offers more comprehensive results. They require significantly less wait time than blood testing, with results typically available in 15–20 minutes. In comparison, the results from a blood test are usually delivered within 1-2 weeks.   While skin testing may seem like the way forward, blood testing offers a unique array of benefits. Patients with sensitive skin hives, eczema, or severe allergic reactions are better candidates for blood testing, as these conditions can cause inaccurate results in skin testing. This type of test is also not affected by medication, meaning that patients who cannot stop taking their medication can still get diagnosed and treated. For skin tests, patients must stop taking certain medications 5-7 days prior, or else the results can be skewed. Blood testing can help those with food allergies identify the exact proteins that are causing their allergic reaction. They can also help patients predict the severity of their allergic reaction, which helps them safeguard their health moving forward.   At Primary Care Center of Clear Lake, we provide the allergy testing that is best suited for your unique needs.
