What's this test for?

This test is ideal if you're experiencing itching, hives, swelling, stomach upset, or breathing issues after eating fish like mackerel. It checks whether your immune system has produced antibodies that react to mackerel, which can be a sign of a fish allergy. It's also useful if you suspect a fish allergy but haven't been able to pin down the exact trigger.

What happens after I get my results?

Your results will show up in your account with your IgE level clearly explained alongside the normal reference range. If your result is positive, a practical next step is to avoid mackerel and watch for reactions to other fish, since cross-reactivity between fish species is common. If your level is very high or you've had a severe reaction like trouble breathing or swelling of the throat, seek medical care right away. You can download a standard lab report anytime and use the trends feature to track changes if you retest later.

What symptoms indicate I may need this test?

Common signs include hives, itching, swelling of the lips or face, stomach cramps, nausea, or vomiting shortly after eating mackerel or other fish. Some people also notice a runny nose, coughing, or wheezing. In more serious cases, symptoms can include difficulty breathing or a rapid drop in blood pressure, which needs urgent attention.

How can I naturally support my immune system if I have a food sensitivity?

While there's no natural way to reverse an allergy, you can support your body by eating a balanced diet rich in fruits, vegetables, and omega-3 sources other than fish, like flaxseed or walnuts. Staying hydrated and managing stress can also help keep your immune system balanced. Always read food labels carefully to avoid hidden mackerel or fish-based ingredients.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification as soon as your report is available in your account. This timeframe allows the lab to accurately measure the specific antibody levels in your blood.

Who should consider this test?

This test is a good fit for anyone who suspects they react to mackerel or other fish, especially if they've had unexplained itching, digestive upset, or breathing symptoms after eating seafood. It's also helpful for people trying to identify which specific fish might be causing symptoms so they can adjust their diet with more confidence.

What does a high result mean?

A high IgE result means your immune system has built up antibodies that recognize mackerel proteins as a threat, which often correlates with a stronger likelihood of an allergic reaction. It doesn't tell you how severe a reaction might be, only that sensitization is present. Combining this result with how your body actually reacts when exposed to mackerel gives the fullest picture.

What causes a positive mackerel IgE result?

A positive result happens when your immune system mistakenly identifies proteins in mackerel as harmful and starts producing IgE antibodies against them. This can develop at any point in life, even if you've eaten fish without issues before. Genetics, other existing allergies, and repeated exposure can all play a role in developing this sensitivity.

How often should I retest?

If you've eliminated mackerel from your diet and want to see if your sensitivity has changed over time, retesting every 1-2 years is a reasonable approach. Retesting sooner may be helpful if you've had a new or worsening reaction. Tracking your results over time in your account can help you spot trends.

What should I do if my results are abnormal?

If your result comes back positive, start by avoiding mackerel and reading ingredient labels closely, since fish is a common hidden allergen in sauces and processed foods. Keep an antihistamine on hand for mild reactions and know the signs of a severe reaction, like swelling or trouble breathing, which requires emergency care. Consider testing for other fish types if you eat seafood regularly, so you know what's safe for you.
