What To Expect During Blood Testing
There are no special preparations for a blood test, which makes it a more convenient option for some. There is also less risk when taking this type of test. Since the allergist is drawing blood and not injecting an allergen, you will not experience an allergic reaction. Blood tests are recommended for people who must take certain medications daily. It is also the best option for those who suffer from severe skin conditions.
During a blood test, an NYC Allergist will insert a small needle and sample a small amount of blood from your vein in your arm. The blood test sample will then be collected in a vial (test tube). This process usually takes less than 5 minutes with minimal to no pain.
