What's this test for?

This test is ideal if you're experiencing bloating, stomach pain, skin reactions, or other unexplained symptoms after eating clams or shellfish dishes. It looks for an immune response (IgG antibodies) to clam proteins, which can help you figure out if clams might be contributing to your ongoing discomfort. It's a helpful next step if you've noticed a pattern between eating clams and feeling unwell but haven't been able to confirm it.

What happens after I get my results?

Your results will show up in your online account, with your clam IgG antibody level explained alongside the normal reference range so you know exactly where you stand. If your level comes back elevated, a practical next step is trying an elimination approach — cutting out clams for a few weeks and tracking how you feel, then retesting later to see if your levels have changed. You can download a standard lab report from your account at any time, and the trends feature lets you track this marker over time if you retest in the future.

What symptoms indicate I may need this test?

Common signs include stomach cramps, bloating, gas, diarrhea, or nausea that shows up after eating clams or shellfish. Some people also notice skin issues like hives, itching, or eczema flare-ups, or general fatigue and brain fog following meals containing clams. If these symptoms keep happening after eating clams specifically, this test can help you connect the dots.

How can I naturally support my digestion around food sensitivities?
If you suspect a clam sensitivity, try removing clams and other shellfish from your meals for two to three weeks and note any changes in your symptoms. Eating smaller, simpler meals and keeping a food-and-symptom journal can help you spot other trigger foods too. Adding gut-friendly foods like fiber, fermented foods, or a probiotic may also support overall digestion while you figure out what's causing your symptoms.
When will I get my results?
Results are typically ready within about 7 days of your lab visit. Once processed, they'll be uploaded directly to your secure online account, and you'll be able to view and download your report as soon as it's available.
Who should consider this test?
This test is a good fit for anyone who regularly eats clams or shellfish and has noticed recurring digestive discomfort, skin reactions, or other symptoms afterward. It's also useful if you're trying to narrow down a list of suspected food triggers as part of a broader elimination diet. People with ongoing unexplained gut or skin issues who haven't found a clear cause may also find this test worth exploring.
What is IgG food sensitivity testing and why does it matter?
IgG is a type of antibody your immune system makes when it reacts to certain proteins, including those found in foods like clams. Measuring IgG levels against clam protein can show whether your body is mounting an ongoing immune response every time you eat it. This matters because repeated exposure to a trigger food can contribute to chronic low-grade symptoms that are easy to overlook or misattribute to other causes.
What does a high clam IgG result mean?
A high result means your immune system is producing more antibodies against clam protein than is typical, suggesting your body may be reacting to it each time you eat clams. This doesn't necessarily mean a severe allergy, but it does suggest clams could be a contributing factor to symptoms like bloating, skin irritation, or fatigue. Many people find that reducing or removing clams from their diet for a few weeks helps them see if symptoms improve.
What causes a high clam IgG level?
A high level usually reflects repeated or frequent exposure to clams, where your immune system has built up a stronger antibody response over time. Some people naturally develop more sensitivity to shellfish proteins than others, even without a classic allergy. Eating clams often, or having a generally more reactive immune system, can both play a role.
How often should I retest?
If you make changes to your diet based on your first result, retesting after 6 to 8 weeks of avoiding clams can help you see if your antibody levels have dropped. If you're not changing your diet, retesting once a year or whenever symptoms change is a reasonable approach. Tracking results over time in your account makes it easy to see the trend.
