What does SPT mean in CLINICAL MEDICINE
Skin Prick Testing (SPT) is a standard medical procedure used to identify the presence of allergies in patients. It involves using a needle to insert a small amount of allergen extract into the skin on the arm or back. After a few minutes, the area is checked for any signs of an allergic reaction, such as swelling or hives. SPT can provide valuable information that helps doctors diagnose and treat allergies better and more effectively.

Definition
In medical terms, SPT stands for Skin Prick Testing. This is an allergy diagnostic technique in which allergens are introduced to the surface of the skin through tiny punctures made by needles or lancets. The allergens may be food items, dust mites, pollens, animal danders, insect venom, and others. After introducing the allergens into the skin surface, it is observed if any reactions occur at those sites through leakage of histamine from mast cells into their surrounding environment which causes redness and inflammation. This allergy can then be diagnosed by interpreting what kind of reactions take place on the skin due to different allergen exposure.
Procedure
The procedure for performing SPT usually starts with preparing allergen samples required for testing using precise concentrations and dilutions based on the patient's history and clinical presentation of symptoms. Following this step, these solutions are transferred onto lancets or needles which will then be inserted into pinpricks made on the surface of the skin being tested. The most commonly used area for allergy tests is on either forearm and sometimes on upper arms also when needed. To ensure accuracy in results, it's important to control enough time between puncture creation and exposure to allergens so that there isn't any change in basal levels of histamine release from mast cells before they come into contact with allergens.
Essential Questions and Answers on Skin Prick Testing in "MEDICAL»CLINICAL"
What is skin prick testing?
Skin prick testing is a type of allergy test used to help identify the cause of an allergic reaction. During the test, a small amount of common allergens are lightly pricked into the surface layer of the skin. This causes a mild reaction that can be monitored to determine if an allergy is present.
Who should get skin prick testing?
Skin prick tests are generally recommended for people who have experienced allergic reactions or those at risk of developing allergies. It's advised for anyone who experiences symptoms such as sneezing, wheezing, coughing, rashes, hives, or difficulty breathing after coming in contact with a certain substance.
How is skin prick testing performed?
During a skin prick test, tiny amounts of specific allergens will be applied on the surface of your forearm or back by using either a sterile disposable syringe or an electronic device that places allergen particles into shallow punctures on your skin.
Does skin prick testing hurt?
No. The aim of this test is to cause only minor irritation and not draw blood so it shouldn't hurt much more than scratches normally feel like. However, there may be some slight itching afterwards which you can easily treat with calamine lotion or hydrocortisone cream.
How long does it take to do skin prick test?
Skin tests usually take less than 15 minutes to complete though sometimes they can take up to 30 minutes depending on how many allergens you need to be tested for. Afterwards, you'll have to wait around 10-15 minutes for the results as swelling and redness around the site indicate an allergic reaction has occurred.
How reliable are skin prick tests?
Skin prick tests are very accurate and reliable when it comes to diagnosing allergies due to their high sensitivity and specificity rate compared with other available methods such as blood tests or elimination diet trials which have lower accuracy rates and are more time consuming.
Are there any side effects associated with skin prick testing?
Generally side effects from this type of testing are minimal but occasionally they can include itching or swelling around the applied area which should subside within hours after removal of the allergen particle(s). Rarely do people experience any further complications beyond these usual symptoms.
Are there any contraindications associated with this test?
This type of allergy diagnosis isn’t suitable for infants under 6 months as their immune system isn’t fully developed yet making them very sensitive to potential allergic reactions due to maturational immaturity in their immune systems therefore avoiding this form of diagnosis altogether would be safest option in this instance
Final Words:
Overall, Skin Prick Testing (SPT) is essential for diagnosing allergies accurately as it helps to determine what type of substances trigger an allergic reaction in an individual's body. With this knowledge, appropriate treatments can be recommended accordingly so that further health complications due to long-term exposure to allergens are avoided down the line.
