Quiz: Test Your Skin Allergy Smarts
Skin allergies happen because:
You don’t have enough histamine
You make antibodies that lead to irritation
You have cells that don’t function properly
Skin allergies happen because:
Got a skin issue? One of many things could be to blame for it, like a virus, bacteria, fungal infection, or an autoimmune disorder like lupus.
Your red, blotchy, or bumpy skin is an allergic reaction only if it’s caused by an allergen -- something your body thinks is an invader. In that case, your immune system makes antibodies. These prompt your body to make chemicals like histamine that cause the reactions.
Which of these can cause a skin allergy?
Pollen
Latex
Cold weather
All of the above
Which of these can cause a skin allergy?
Almost anything can set off an allergic skin reaction in people with sensitive immune systems.

If you touch poison ivy, you’ll always get a rash:
True
False
If you touch poison ivy, you’ll always get a rash:
You’re not guaranteed to get an itchy annoyance. It’s usually about a 50-50 shot. It’ll depend on how much ivy you came in contact with and what part of your body touched it. Certain spots, like your face, are extra sensitive.
You also might fall into the small but lucky group of people -- about 15% of us -- who aren’t allergic to urushiol, the irritating oil that coats poison ivy leaves.
Not so lucky? You may start seeing red anywhere from 4 hours to 4 days after your run-in.
Children with eczema are more likely to get:
Hay fever
Food allergies
Asthma
All of the above
Children with eczema are more likely to get:
You may hear your doctor mention something called “atopic march.”
It basically means that allergic conditions like the ones listed above can get stronger as you get older. Eczema usually gets better with age.
Jewelry made with which metal is most likely to cause an allergic reaction?
Aluminum
Nickel
Rhodium
Jewelry made with which metal is most likely to cause an allergic reaction?
Nickel, most commonly found in costume jewelry, is known for causing something called “allergic contact dermatitis.” That’s a reaction that happens when you touch something you’re allergic to.
Other common triggers for it include:
- Soap
- Shampoo
- Laundry detergent
If you’re allergic to copper, you may also react to:
Aluminum
Titanium
14K gold
If you’re allergic to copper, you may also react to:
Gold on its own is pretty soft. Other metals are often added to it to make it stronger. The 14-karat kind is only about 58% gold. The rest is a combination of metals. Those may include allergens like copper and nickel.
If you’re allergic to shellfish, you’ll get hives the first time you eat shrimp.
True
False
If you’re allergic to shellfish, you’ll get hives the first time you eat shrimp.
Food allergies sometimes show up in the form of hives, in some cases with more serious things like swelling of the tongue, vomiting, and trouble breathing. But none of this happens the first time you’re exposed to an allergen, including food.
When you first eat or touch an allergen, your immune system decides it’s dangerous and makes antibodies against it. This gets your body ready to react the next time you touch it.
Some things can give you a reaction only after you use them and then go out in the sun.
True
False
Some things can give you a reaction only after you use them and then go out in the sun.
It’s called “photoallergic contact dermatitis,” and here’s how it works: You’re exposed to an allergen, which might be in your shaving cream, lotion, perfume, or even in a food that touches your skin.
That allergen by itself doesn’t bug you enough to cause a reaction, but when the sun hits your skin, the combination causes you to break out in a rash.
Which test is commonly used to diagnose skin allergies?
A prick test
A patch test
A blood test
Which test is commonly used to diagnose skin allergies?
Your doctor will put patches on your arm or back that contain 20 to 30 extracts of allergens that cause reactions. You’ll wear the patches for 48 hours before your doctor removes them. If you have irritation in those areas, it usually means you’re allergic to those things.
The best way to avoid getting allergy symptoms is:
Stay away from the allergen
Take allergy tests regularly
Stay in touch with your doctor
The best way to avoid getting allergy symptoms is:
Once you figure out what’s irritating your skin, your best bet is to avoid it. But accidents happen. It’s also not always possible to dodge everything you’re allergic to. When a reaction crops up, a cream or ointment that you put on your skin should help calm things down.
In some cases -- like when a reaction leads to a widespread rash -- you might need to see your doctor and have them prescribe a medicine called prednisone, which you’d take in pill form.
