First of all, if you are looking for allergy skin testing near me in Southfield, chances are that double-checking in your pocket is insufficient. Read more about the trigger of your symptoms, if any, know whether skin testing is appropriate next, and where to obtain a suitable assessment.
Allergy skin testing can assist in identifying substances possibly linked to symptoms such as sneezing, itchy or watery eyes, hives, certain rashes, or reactions to foods, medications and insect stings, and allergens in the environment. However, the test itself is just part of a diagnosis. It depends on your symptoms, background, whether you are taking any medications already, and what type of reaction you have. The American College of Allergy, Asthma & Immunology (ACAAI) recommends combining allergy testing with the medical history and physical examination rather than relying solely on a positive reaction to skin prick testing.
Our services are available at NovaHealth Urgent Care in Southfield for allergies, minor allergic reactions, eczema or dry skin, and rashes or other skin conditions. Some of the testing we offer, such as skin prick, intradermal or patch testing, is not specifically listed on our service list below, so patients looking specifically for allergy skin testing should call ahead to clarify what tests are available and if an allergist may be a more appropriate next step.
Key Takeaways
- Allergy skin testing may help identify potential triggers, but results should be looked at in conjunction with your symptoms and medical history.
- Skin prick testing typically results are within about 15 to 20 minutes, while patch testing looks for a delayed skin reaction over the course of a couple of days.
- Antihistamines and some other medicines can affect skin-test results; ask the provider who is testing you what medications to avoid and how long before the test, instead of simply switching your meds on your own.
- A positive skin test indicates sensitization to an allergen but does not in and of itself determine that the material produces symptoms with common exposure.
- If you’re looking for allergy skin testing near Southfield, be sure that the office offers the specific test you need before making the trip.
What Is Allergy Skin Testing?
Allergy skin testing exposes a small area of your skin to suspected allergens and checks for a reaction. The goal is to help determine which substances may be contributing to your symptoms.
An allergen can be something you breathe, eat, touch, or encounter in your environment. Depending on your symptoms, testing may involve pollen, mold, dust mites, pet dander, foods, insect venom, medications, or substances that commonly cause contact dermatitis.
Skin testing is not meant to screen randomly for every possible allergy. A healthcare professional should first consider your symptoms and history, then choose allergens that are relevant to your situation. The American Academy of Allergy, Asthma & Immunology (AAAAI) specifically notes that allergy testing should be guided by a healthcare professional with appropriate allergy and immunology training.

What Types of Allergy Skin Tests Are Available?
The three tests people commonly encounter are skin prick testing, intradermal testing, and patch testing. They do different jobs, so the right test depends on the suspected trigger and the type of reaction you have.
Skin Prick or Scratch Testing
Skin Prick Test (SPT): If allergies seem immediate in nature, this is often the test used to find out more about it.
Small drops with possible allergens are added on the forearm or on the back. Next, a small lancet is used to barely prick the skin so that the allergen comes in contact with the skin’s surface.
You sit for roughly 15 minutes before the provider looks at it. A mild reaction results in a small, red, raised, itchy spot like that of a mosquito bite.
Skin prick testing may be used when evaluating possible reactions to substances such as:
- Pollen
- Mold
- Dust mites
- Pet dander
- Certain foods
The testing itself typically causes only mild, brief discomfort.
Intradermal Allergy Testing
An intradermal test places a small amount of allergen just under the skin with a thin needle.
This approach may be considered when a skin prick test is negative but the person’s history still raises concern about a particular allergy. Intradermal testing is also used in certain evaluations involving insect venom or medications such as penicillin.
Because intradermal testing is more sensitive, the decision to use it should come from a healthcare professional who can determine whether it is appropriate for the suspected allergy.
Patch Testing
A patch test is different because it looks for delayed reactions rather than the immediate reactions evaluated by prick testing.
Small amounts of suspected contact allergens are placed on adhesive patches, which are usually applied to the back. The patches commonly remain in place for about 48 hours, and additional follow-up may be needed because some reactions take several days to become visible.
Patch testing can be useful when recurring dermatitis may be related to substances such as:
- Fragrances
- Metals such as nickel
- Preservatives
- Hair dyes
- Latex
- Ingredients in skin-care or personal-care products
If your main concern is a recurring rash after something touches your skin, patch testing may be more relevant than a standard skin prick test.
How Do I Find the Right Allergy Skin Testing Near Me?
When searching for allergy skin testing near me, start by finding out what type of testing the office actually performs.
An office that treats allergy symptoms does not necessarily perform comprehensive allergy skin testing. Before scheduling, ask several practical questions:
- Do you perform skin prick testing, intradermal testing, patch testing, or all three?
- Will an allergist interpret my results?
- Which medications should I stop before the appointment?
- What allergens will I be tested for?
- Will testing and interpretation happen during the same visit?
- Does my insurance require a referral or prior authorization?
ACAAI states that skin tests are typically performed in an allergist’s office and should be conducted by trained practitioners who understand both the procedure and its risks.
That distinction matters. If you already know that you need comprehensive allergy testing, an allergy specialist may be the most direct choice. If you are not yet sure whether your symptoms are caused by allergies—or you are currently dealing with a mild rash, hives, congestion, or another non-emergency problem—an initial medical evaluation can help determine what kind of follow-up makes sense.
How Should I Prepare for Allergy Skin Testing?
Your testing provider should give you specific instructions before the appointment. Do not stop prescription medications without asking the healthcare professional who manages them.
Ask About Antihistamines
Antihistamines can suppress the skin’s response to an allergen and make a skin test harder to interpret.
Depending on the medication, patients may be told to stop an antihistamine several days before testing. ACAAI notes that many patients are advised to avoid most antihistamines for approximately three to seven days, but the timing varies by medication. Some drugs may need a different interval.
That is why a blanket rule such as “stop everything for seven days” is not appropriate.
Give the testing office a complete list of:
- Prescription medications
- Over-the-counter allergy medicines
- Sleep aids or cold medicines that may contain antihistamines
- Psychiatric medications
- Asthma medications
- Supplements you take regularly
Some medications should not be stopped without medical guidance.
Ask Which Medications You Can Continue
Nasal steroid sprays and many asthma medicines do not interfere with skin-test results in the same way antihistamines do, according to ACAAI. Still, confirm your medication instructions with the office performing your test.
Arrive With Your Allergy History
A good allergy evaluation starts before the first skin prick.
Think about:
- When your symptoms occur
- Whether they are seasonal or year-round
- Foods eaten before a reaction
- New medications
- Pets in the home
- Work or hobby exposures
- Skin-care or household products that touch your skin
- Insect stings
- Previous severe reactions
- What seems to make symptoms better or worse
These details can help the provider choose useful tests instead of testing broad groups of allergens that may have little connection to your symptoms.
What Does a Positive Allergy Skin Test Mean?
A positive skin test means your skin reacted to a particular allergen, but the result does not automatically prove that substance is causing your real-world symptoms.
For skin prick testing, providers compare the reaction to controls. Histamine is commonly used as a positive control because most people’s skin should react to it, while saline or another neutral solution serves as a negative control. These controls help the provider determine whether the test can be interpreted reliably.
The size of the resulting wheal, or raised bump, is measured.
However, test results still need context. Both Mayo Clinic and ACAAI caution that false-positive and false-negative results can occur. Someone can test positive to a substance without developing symptoms during normal exposure.
A useful diagnosis therefore combines:
Your symptoms + your exposure history + your physical evaluation + your test results
This is one of the biggest reasons to choose a provider who can interpret the test rather than simply report which spots became red.
What If I Cannot Stop My Allergy Medication?
Tell the provider before the test. Do not simply stop an important medication on your own.
When skin testing would be unreliable or inappropriate, an allergy blood test may sometimes be considered instead. Blood testing can also be useful for people whose medications cannot be discontinued or whose skin condition may interfere with skin testing.
Skin and blood testing are not interchangeable in every situation. Your medical history and suspected allergen should guide the choice.

Should I Go to Urgent Care or an Allergist for Allergy Symptoms?
For targeted allergy skin testing and ongoing identification of allergy triggers, an allergist is likely the more appropriate provider. Assessing and treating many of today’s most common non-emergency symptoms is the job of an urgent-care clinic.
At NovaHealth Urgent Care, you can get treatment for allergies, mild allergic reactions, eczema or dry skin, insect and bee stings (bites), rash or other skin problems.
And if you visit us in October 2023 with current symptoms and don’t think the cause is a health concern, we can assess this directly. Please call to check if this test is offered before you come in if your primary reason for coming is a skin prick, intradermal, or patch test.
This can save you a trip that would have been avoided and allow you to receive the appropriate level of care in a more timely fashion.
When Is Allergy Testing Not the First Priority?
Allergy testing is intended to investigate triggers when you are medically stable. A severe allergic reaction requires immediate treatment instead.
If you are experiencing a serious allergic reaction—especially significant trouble breathing or another rapidly worsening reaction—seek emergency medical care rather than waiting for routine allergy testing. Severe allergic reactions may require epinephrine and emergency treatment.
NovaHealth’s published information likewise distinguishes minor allergic reactions, which may be appropriate for urgent care, from severe anaphylaxis, which requires a higher level of emergency care.

Frequently Asked Questions
How long does allergy skin testing take?
Skin prick and intradermal test reactions are commonly checked after about 15 to 20 minutes. The overall appointment may take longer because the provider also needs to review your symptoms, medical history, medications, and results. Patch testing requires multiple days because it evaluates delayed reactions.
Does an allergy skin test hurt?
Most people experience only mild, brief discomfort from skin prick testing. If you react to an allergen, the testing spot may become itchy and develop a small bump similar to a mosquito bite.
Do I have to stop antihistamines before an allergy test?
Often, yes. Antihistamines can suppress the skin reaction used to interpret the test. However, the required stop time depends on the medication, and some other medicines should not be stopped without medical supervision. Ask your testing provider for instructions specific to your medications.
Can allergy skin testing diagnose a food allergy by itself?
No. A positive skin test alone does not establish that a food causes symptoms when eaten. Allergy testing needs to be interpreted in the context of your medical and reaction history, and additional evaluation may sometimes be necessary.
What if all my allergy skin tests are negative?
Negative testing may mean the tested allergens are not responsible, but a provider may also consider whether medication, a skin condition, an untested allergen, or a nonallergic condition could explain the symptoms. In some circumstances, additional testing may be appropriate.
Can urgent care perform allergy skin testing?
Services vary by clinic. Some urgent-care centers evaluate and treat allergy symptoms without offering specialized skin testing. NovaHealth’s current published service list includes allergies and minor allergic reactions but does not specifically list skin prick, intradermal, or patch testing. Call us before visiting if allergy skin testing is your primary reason for the appointment.
