Allergenic testing for 6 month old babies involves drawing venous blood, not fingertip blood, depending on the baby’s blood vessels.
Allergenic testing for 6 month old babies is mainly an in vitro test, usually using venous blood or body fluids. Venous blood is drawn from the back of the hand, elbow, ankle, neck and other parts of the body.
Small infant babies with thin blood vessels may also choose a scalp vein. The amount of blood drawn is usually around 2 ml, and the serum is separated from the blood cells after drawing. Due to the very wide range of allergens, it is not possible for allergen testing to detect all allergens.
When testing your baby for allergens, it is also important to note that you need to stop using anti-allergy medications such as loratadine syrup 1 week prior to the test so as not to affect the results.
