Are Allergy Tests Painful? What to Expect

Last updated
April 15, 2025

Parents naturally worry about whether allergy testing will cause their child discomfort. Understanding what to expect can help ease these concerns and prepare both you and your child for the experience. At LACK Clinic, we prioritise your child's comfort throughout the testing process while ensuring we gather the accurate diagnostic information needed to guide their care.

How skin prick tests feel

Skin prick testing is the most common method of allergy testing and involves placing a small drop of allergen extract on the skin, then making a tiny prick through the drop.

For infants and toddlers

Very young children typically experience minimal discomfort during skin prick testing. What we observe is that:

     
  • The actual prick sensation is so mild that babies often don't react to it
  • Most infants are more bothered by having their arm or back held still during the procedure
  • The testing process itself takes only about 5 minutes
  • Distraction techniques like toys, singing, or feeding can help keep babies calm

For older children

Children who can communicate their experiences generally report that skin prick testing:

     
  • Feels like a light scratch rather than a needle
  • Creates a mild tickling or itching sensation rather than pain
  • Is much less uncomfortable than they anticipated

Many children are initially anxious about the unknown, but our allergy nurses are experienced in explaining the procedure in age-appropriate terms and demonstrating it first to alleviate fears.

Safety of skin prick testing

Parents sometimes worry that introducing allergens during testing might trigger a severe reaction. It's important to understand that:

     
  • Skin prick tests are extremely safe and rarely cause systemic reactions
  • The amount of allergen introduced is minimal and limited to the skin's surface
  • Severe reactions or anaphylaxis from skin testing are exceedingly rare
  • Our clinic is fully equipped to manage any allergic symptoms that might occur

After the test, some children develop:

     
  • Local itching at test sites (the most common response)
  • Redness and swelling at positive test sites
  • Occasionally, mild sneezing or eye itching

These symptoms typically resolve quickly, either on their own or with antihistamine medication if needed. Any discomfort is usually brief and easily managed.

What to expect during blood tests

Some children require blood testing (specific IgE testing) as part of their allergy assessment. We understand that blood draws can cause anxiety, especially for younger children, and we take several measures to minimise discomfort.

Numbing cream makes a difference

For blood tests, we offer topical anaesthetic cream (EMLA) to numb the skin before the needle is inserted:

     
  • The cream is applied to the skin and covered with a small clear dressing
  • It remains in place for about an hour to take full effect
  • After removal, the skin is numb, significantly reducing the sensation of the needle
  • This cream is safe for children of all ages, though it shouldn't be used if your child has had a prior reaction to it

Expert technique matters

Our phlebotomists (specialists in taking blood samples) are highly experienced in working with children:

     
  • They use age-appropriate distraction techniques
  • They employ the smallest needles appropriate for the test
  • They work quickly and efficiently to minimise the time involved
  • They are skilled at successful first attempts, reducing the need for multiple tries

Following a blood test, a small bruise may develop at the site, but this typically fades within

Preparing for your appointment

A little preparation can help ensure the testing process goes smoothly:

Before skin prick testing

  • Avoid antihistamine medications for the recommended period before testing (typically 3–7 days, depending on the specific medication)
  • Continue all other regular medications unless specifically advised otherwise
  • Apply moisturiser to eczema-affected skin (but not to the testing area on the testing day)
  • Eat normally before the appointment

Before blood testing

  • No special medication restrictions are necessary
  • Consider applying numbing cream before your appointment (if provided)
  • Ensure your child is well-hydrated, which can make veins easier to access
  • A light meal beforehand can help prevent light-headedness

For all appointments

  • Bring your child's favourite comfort items
  • Allow extra time to avoid rushing and adding stress
  • Consider bringing a second adult if you have other children to supervise
  • Be prepared to comfort and distract your child during waiting periods

Looking beyond the testing experience

While momentary discomfort during testing is a common concern, it's helpful to maintain perspective on the broader benefits:

Accurate diagnosis

Properly conducted allergy testing provides crucial information that:

  • Identifies specific triggers causing your child's symptoms
  • Rules out suspected allergens that aren't actually problematic
  • Guides precise, targeted treatment plans
  • Helps prevent unnecessary dietary or lifestyle restrictions

Improved quality of life

The temporary discomfort of testing is balanced against the potential for:

  • Relief from chronic allergy symptoms
  • Prevention of serious allergic reactions
  • More confidence in managing your child's condition
  • Clearer guidance for schools and caregivers

What parents tell us after testing

Many parents share their relief after testing is complete, often reporting:

  • "It wasn't nearly as bad as we expected"
  • "The numbing cream made such a difference"
  • "The staff's approach really helped my anxious child"
  • "Having clear answers was worth the brief discomfort"

These perspectives highlight that while concerns about testing discomfort are valid, the actual experience is typically much more manageable than anticipated, and the benefits of clear diagnosis substantial.

Moving forward with confidence

Understanding your child's specific allergic triggers through appropriate testing provides a foundation for effective management. With accurate results in hand, you and your allergist can develop a tailored plan that addresses your child's unique needs.

Remember that at LACK Clinic, our goal extends beyond simply conducting tests – we aim to provide a supportive experience that establishes trust and confidence as we partner with you in your child's allergy care journey. The brief moments of testing are just one small part of our comprehensive approach to helping your child thrive despite their allergic condition.
