What's this test for?

This test is ideal if you or a specialist are investigating unusual cells found in a tissue sample and need more information about their origin. CD43, IHC with Interpretation is a specialized pathology test that helps identify certain types of blood and immune cell abnormalities, including some lymphomas and leukemias. It's typically ordered as a follow-up to a biopsy or other tissue sample that showed something worth a closer look.

What happens after I get my results?

Your results will appear in your account along with an explanation of what the finding means for the tissue sample tested. Because this is a specialized interpretive test, the report will describe whether the marker was present or absent and what that can suggest about the cells examined. You can download the full lab report from your account at any time, and if further testing or monitoring is recommended, that guidance will be included in the report. If your results show anything concerning, it's a good idea to arrange follow-up testing promptly.

Who should consider this test?

This test is generally considered when a previous biopsy or tissue sample showed atypical cells that need further classification. It's often used alongside other immunohistochemistry (IHC) markers to build a fuller picture of what's happening at the cellular level. People already working through a diagnostic workup for a suspicious lump, swollen lymph node, or abnormal blood cell finding are the typical candidates.

What symptoms indicate I may need this test?
Symptoms that might lead to this type of tissue testing include an unexplained lump or swelling, persistent swollen lymph nodes, unusual fatigue, unexplained weight loss, or abnormal results from a prior blood or tissue test. These symptoms alone don't mean you need this specific test — it's usually ordered after initial findings point toward a need for deeper tissue analysis. If you're experiencing these symptoms, addressing them with further testing sooner rather than later is a smart step.
When will I get my results?
Results for this test are typically available within about 7 days. This timeframe reflects the detailed lab work involved in preparing and interpreting the tissue sample. You'll be notified as soon as your report is ready to view in your account.
What is CD43 and why does it matter?
CD43 is a protein found on the surface of certain white blood cells. Pathologists use it as a marker to help tell different cell types apart when looking at a tissue sample under a microscope. Identifying whether CD43 is present or absent can help narrow down what type of cell abnormality is present, which is valuable information for understanding a diagnosis.
How can I naturally support my immune system while awaiting results?
While waiting for specialized test results, focus on habits that generally support immune health: eat a balanced diet rich in fruits and vegetables, stay hydrated, get consistent sleep, and manage stress through light activity or relaxation techniques. Avoid smoking and limit alcohol, since both can affect immune function. These steps won't change your test result, but they support your overall well-being during a stressful waiting period.
What does a positive CD43 result mean?
A positive result means the CD43 marker was detected in the tissue sample, which can point toward specific types of blood or immune cell conditions, including certain lymphomas. This finding is usually interpreted alongside other markers and clinical information rather than on its own. If your result is positive, prompt follow-up testing is recommended to get a complete picture.
What should I do if my results are abnormal?
If your results come back abnormal, review the detailed interpretation included in your report to understand what was found. Consider scheduling follow-up testing to confirm the finding and gather more information. If you notice new or worsening symptoms like rapid swelling, fever, or severe fatigue, seek medical care promptly.
How often should I retest?
Retesting frequency depends on the original reason for testing and what the results show. If your result is inconclusive or positive, follow-up testing is often recommended soon after to confirm the finding. If results are clear and no new symptoms develop, retesting typically isn't needed unless something changes.

What this means

A negative result means the CD43 marker was not detected in the tissue sample examined. This generally makes certain types of blood and immune cell abnormalities less likely, though your interpretation should be viewed alongside any other tests you've had done.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
