What's this test for?

This test is ideal if you're experiencing unexplained lymph node swelling, unusual blood cell counts, or other findings that need further characterization at the cellular level. It's often used as a follow-up step when a prior test or biopsy pointed to something unusual with your blood or immune cells. This test helps identify what type of cells are present, which is an important piece of the puzzle in diagnosing certain blood and immune system conditions.

What's included in this test?

This test uses a panel of CD (cluster of differentiation) markers that are proteins found on the surface of different blood and immune cells. By checking which markers are present or absent, this test helps characterize an unknown cell type, which matters because different cell types point to different underlying conditions. The results come with an expert interpretation to help make sense of the pattern of markers found.

What happens after I get my results?

Your results will be available in your account, with an explanation of what each marker result means. Because this is a specialized diagnostic test, next steps often involve additional testing or specialist input depending on which markers are present or absent. The full lab report, including the detailed interpretation, is downloadable from your account at any time. You can also track results over time using the trends feature if repeat testing is needed.

How can I naturally support my immune system?

While this test is diagnostic and not something lifestyle changes can alter, supporting your overall immune health is still worthwhile. Eating a balanced diet rich in fruits, vegetables, and lean protein, getting regular sleep, staying active, and managing stress all help your immune system function well. Avoiding smoking and excessive alcohol also supports healthy blood cell production.

When will I get my results?

Results for this test are typically available within about 7 days of your sample being processed at the lab. This timeframe reflects the detailed nature of immunohistochemistry testing, which requires careful lab analysis and expert interpretation. You'll be notified as soon as your results are ready to view in your account.

Who should consider this test?

This test is generally considered when a previous test, biopsy, or blood work result has flagged something unusual that needs further cell-level characterization. It's often used as a next step for people with unexplained lymph node changes, abnormal blood counts, or suspicious cell samples. It's less of a standalone screening test and more of a targeted diagnostic tool.

What symptoms indicate I may need this test?

Symptoms like persistent, unexplained swelling of lymph nodes, unusual fatigue paired with abnormal blood work, unexplained weight loss, or night sweats can sometimes lead to this type of specialized testing. These symptoms alone don't mean you need this specific test, but they're often what prompts the earlier workup that leads here. This test is typically ordered as a follow-up rather than a first step.

What is IHC and why does it matter?

IHC stands for immunohistochemistry, a lab technique that uses special markers to "tag" specific proteins on cells so they can be identified under a microscope. It matters because different cells carry different combinations of these markers, almost like a fingerprint, which helps pinpoint exactly what type of cell is being looked at. This is especially useful when trying to understand blood or immune system related conditions.

How often should I retest?

This is not typically a routine or repeat test — it's usually done once to help characterize a specific finding. If retesting is needed, it would generally be based on new symptoms or findings from other blood work rather than on a set schedule. Your results report will note if any follow-up testing is suggested.

What should I do if my results are abnormal?

If your results show an unusual pattern of markers, the report will explain what that pattern typically indicates in simple terms. Because this is a specialized diagnostic result, it's a good idea to pair it with your other recent blood work when reviewing next steps. If you notice severe symptoms like rapid swelling, high fever, or extreme fatigue, seek medical care right away.
