Scratch/Prick and Intradermal Testing for Allergy Diagnosis
Steps Involved in IVF:
Procedure Description
Allergies affect millions of individuals worldwide, with symptoms ranging from mild discomfort to severe, life-threatening reactions. Identifying the source of an allergy is crucial for effective treatment, and allergy testing plays a central role in this process. Two of the most common types of allergy testing are scratch/prick testing and intradermal testing. Both methods allow healthcare providers to accurately identify specific allergens that trigger reactions in patients, offering a targeted approach to managing allergies.
Scratch/Prick Testing is generally the first-line procedure to screen for allergic reactions. In this test, small amounts of potential allergens are applied to the skin, typically on the forearm or back, through tiny punctures or scratches. The healthcare provider observes the skin’s reaction over a brief period, watching for redness or swelling that indicates an allergic response. This test is often used for common allergens like pollen, pet dander, dust mites, and certain foods.
Intradermal Testing, on the other hand, is usually performed when more sensitive testing is required, especially if initial scratch/prick tests yield inconclusive results. During intradermal testing, a small amount of allergen is injected just below the skin's surface. Intradermal testing allows for greater sensitivity, especially for detecting allergens like insect venom or medications. While both tests are relatively quick and straightforward, they provide different levels of sensitivity, which helps determine the most suitable method for each patient.
Procedure Duration
The duration of allergy testing varies based on the type of test, number of allergens tested, and the patient’s skin reactivity. Scratch/prick testing generally takes around 20 to 40 minutes. The actual preparation and application of allergens take only a few minutes, but patients need to wait for any reaction to develop, typically within 15-20 minutes. This waiting period is essential for observing any skin reactions, which indicate potential allergens.
In intradermal testing, each allergen injection takes a few seconds, but because the procedure involves injecting allergens below the skin surface, it can take longer than scratch testing, especially if multiple allergens are tested. The reactions from intradermal tests also typically develop within 15-20 minutes. Patients should be prepared to stay at the clinic for at least 30-60 minutes, depending on the number of allergens tested.
For both testing methods, recovery is minimal, with only minor skin irritation that usually subsides within hours. Patients may be asked to avoid antihistamines or certain medications before the test, as these can interfere with results. Post-test care is straightforward, often requiring only basic skin care, like applying a gentle moisturizer or avoiding irritating substances.

Risks & Considerations
- Risk of Allergic Reaction: Though rare, there is a slight risk of a more intense allergic reaction during testing, especially in intradermal tests, requiring immediate medical response.
- Skin Irritation: Mild itching, redness, or swelling at the test site is common and usually subsides within hours.
- False Positives/Negatives: Some patients may have false-positive or false-negative results, which can complicate diagnosis.
- Medication Interference: Certain medications, like antihistamines, can interfere with results, so patients may need to stop these before testing.
- Not Suitable for All Patients: Patients with severe skin conditions or certain chronic health issues may need alternative testing methods, as skin-based tests may not be safe or accurate for them.
How to Choose the Right Doctor and Hospital
When selecting a provider for allergy testing, it’s essential to seek a qualified specialist, such as a board-certified allergist with experience in allergy testing and management. Look for facilities that adhere to international standards and are accredited by reputable healthcare organizations, ensuring high standards in patient care and diagnostic accuracy.
Consider the hospital’s or clinic’s expertise in allergy diagnostics, particularly if you require advanced testing like intradermal testing. Review patient testimonials, check online reviews, and confirm that the healthcare team is experienced in handling allergic reactions, as safety and accurate interpretation of results are paramount in allergy testing.

Frequently Asked Questions
What actually happens during hyperstimulation of the ovaries?
The patient will take injectable FSH (follicle stimulating hormone) for eight to eleven days, depending on how long the follicles take to mature. This hormone is produced naturally in a woman’s body causing one egg to develop per cycle. Taking the injectable FSH causes several follicles to develop at once, at approximately the same rate. The development is monitored with vaginal ultrasounds and following the patient’s levels of estradiol and progesterone. FSH brand names include Repronex, Follistim, Menopur, Gonal-F and Bravelle. The patient injects herself daily.
What happens during egg retrieval?
When the follicles have developed enough to be harvested, the patient attends an appointment where she is anesthetized and prepared for the procedure. Next, the doctor uses an ultrasound probe to guide a needle through the vaginal wall and into the follicle of the ovary. The thin needle draws the follicle fluid, which is then examined by an embryologist to find the eggs. The whole process takes about 20 minutes.
What happens to the eggs?
In the next step, the harvested eggs are then fertilized. If the sperm from the potential father, or in some cases, anonymous donor, has normal functionality, the eggs and sperm are placed together in a dish with a nutrient fluid, then incubated overnight to fertilize normally. If the sperm functionality is suboptimal, an embryologist uses Intracytoplasmic Sperm Injection to inject a single sperm into a single egg with an extremely precise glass needle. Once fertilization is complete, the embryos are assessed and prepared to be transferred to the patient’s uterus.
How are the embryos transferred back to the uterus?
The doctor and the patient will discuss the number of embryos to be transferred. The number of successfully fertilized eggs usually determines the number of eggs to be placed in the uterus. Embryos are transferred to the uterus with transabdominal ultrasound guidance. This process does not require anesthesia, but it can cause minor cervical or uterine discomfort. Following transfer, the patient is advised to take at least one days bed rest and two or three additional days of rest, then 10 to 12 days later, two pregnancy tests are scheduled to confirm success. Once two positive tests are completed, an obstetrical ultrasound is ordered to show the sac, fetal pole, yolk sac and fetal heart rate.
Embryoscope©
Built into this technology there is a microscope with a powerful camera that allows the uninterrupted monitoring of the embryo during its first hours of life. In this way, we can keep a close eye on the embryo, from the moment when the oocyte is inseminated and begins to divide into smaller and smaller cells, until it can be transferred to the uterus.
