The full form of ANST in medical term is “After Negative Skin Test.”
A negative skin test means that there was no visible reaction to the allergen during the test. This result indicates that the person is not allergic to that specific substance. It is vital to note that a negative result does not necessarily mean that the person is not allergic to other substances, nor does it guarantee that the person will never develop an allergy.
If you receive a negative skin test, discussing the results with your healthcare provider is important. Depending on your symptoms and medical history, they may recommend further testing or treatment. It is important to continue to monitor your symptoms and seek medical attention if you experience any changes or new symptoms.
Sometimes, a negative skin test may mean someone has outgrown an allergy. It is important to continue to avoid the allergen until further testing or evaluation has been completed.
If you previously avoided certain foods or substances due to suspected allergies, you could reintroduce them into your diet or routine.
False negatives can occur when the test is performed during an active allergic reaction. A negative skin test does not necessarily rule out a food allergy; some food allergies do not produce a visible skin reaction. Other diagnostic tests may be necessary to confirm or rule out an allergy in these cases.
