What's this test for?

This test is ideal if you're being evaluated for a blood-related cancer, such as a lymphoma or plasma cell disorder, and a tissue sample needs closer analysis. CD38 IHC (immunohistochemistry) looks at a tissue sample under specialized staining to see how much of the CD38 marker is present on cells. It's typically ordered as a specialized follow-up test rather than a first-line screening test.

What's included in this test?

This test uses immunohistochemistry (IHC) to detect the CD38 protein marker directly on a tissue sample. Looking at how cells express CD38 helps characterize certain blood cell abnormalities, since this marker is commonly found on plasma cells and some white blood cells. It's a targeted, single-marker stain rather than a broad panel.

What happens after I get my results?

Your results will be available in your account, and the report explains what the findings mean in plain language. Because this is a specialized tissue stain without an included interpretation, the raw pathology findings are what you'll see — next steps often depend on discussing the findings with the person coordinating your care. You can download the standard lab report anytime from your account, and if you need related testing again in the future, you can track results over time using the trends feature.

How can I naturally support healthy immune and blood cell function?

While a CD38 IHC test result depends on the tissue sample already collected and isn't changed by lifestyle habits, keeping your immune system strong overall is still worthwhile. Eating a nutrient-rich diet, staying hydrated, getting consistent sleep, and avoiding smoking all support healthy blood cell function. Regular movement and stress management also help your body's natural defenses work well.

When will I get my results?

Results for this test are typically ready within about 7 days, since tissue staining and specialized review take longer than a standard blood test. You'll receive a notification once your report is ready to view in your account. If your situation feels urgent, don't wait on results — seek medical care right away.

Who should consider this test?

This test is generally considered when there's already a reason to look closely at a tissue sample for a blood-related condition, such as a suspected lymphoma, leukemia, or plasma cell disorder. It's not typically a first-step or routine screening test for the general public. People already undergoing a workup for an unusual blood cell finding are the main audience for this specific stain.

What symptoms might lead someone to need this test?

Symptoms like unexplained swollen lymph nodes, persistent fatigue, unexplained weight loss, bone pain, or abnormal findings on a prior blood test or biopsy are common reasons this type of specialized tissue testing gets ordered. These symptoms alone don't diagnose anything specific, but they're often what prompts a closer look at tissue samples. This test is one piece of a larger diagnostic picture rather than a standalone screening tool.

What is CD38 and why does it matter?

CD38 is a protein found on the surface of certain blood cells, especially plasma cells and some white blood cells. Pathologists look at how much CD38 is present because certain cancers and blood disorders show unusually high (or sometimes altered) levels of this marker. It's a useful clue that, combined with other findings, helps characterize what's happening in a tissue sample.

How often should I retest with this type of test?

This isn't a routine or repeat-on-a-schedule test — it's usually ordered once for a specific diagnostic question tied to a particular tissue sample. If new symptoms or findings arise later, additional testing (not necessarily this exact test) may be recommended at that time. There's no standard retesting interval like there would be for a routine blood panel.

What should I do if my results raise concerns?

If your CD38 IHC report shows unusual findings, treat this as important information to act on rather than something to sit with. Keep a copy of your downloadable lab report handy, and use it alongside any other test results you have to get a fuller picture of what's happening. If you have concerning or worsening symptoms in the meantime, seek medical care promptly.
