Tumor Markers

Prostate-Specific Antigen (PSA) is a protein measured in blood as part of a PSA test. It is commonly used in a Tumor Markers panel and is reported on a lab report with a numeric result and unit. PSA values are interpreted against a normal range, and changes can reflect factors that influence prostate tissue activity and blood levels.

Carcinoembryonic Antigen (CEA) is a lab value used as a tumor marker in blood. CEA on a blood test reflects how much of this marker is present in the sample, and results are often read as part of a broader Tumor Markers panel. Normal Carcinoembryonic Antigen values are usually listed in ng/mL, and the Carcinoembryonic Antigen reference range can vary by lab method and reporting system.

Cancer Antigen 125 (CA-125) is a blood marker measured as part of some tumor marker panels. CA-125 on a lab report is often used to track changes over time, and results are read with the full clinical context, not by the number alone.

Alpha-Fetoprotein (AFP) is a lab measurement reported on some blood tests and tumor marker panels. AFP on a lab report helps show how much of this protein is present in the blood, with results compared against an AFP normal range or Alpha-Fetoprotein reference range. Higher or lower AFP test values can reflect changes in protein production, blood volume, or other body-state factors.

Cancer Antigen 19-9 (CA 19-9) is a blood marker measured on a lab report as part of tumor marker testing. It is used to show the amount of CA 19-9 present in the blood, which can vary with body chemistry and testing context. On a blood test, CA 19-9 is usually read alongside other markers and the Cancer Antigen 19-9 normal range.

Beta Human Chorionic Gonadotropin (β-hCG) is a lab value that measures a hormone-like signal found in blood. On a blood test, β-hCG is commonly reported as part of a tumor markers panel and is used to track how much of this marker is present on a lab report. It can vary based on age, sex, pregnancy status, and lab method.

Cancer Antigen 15-3 (CA 15-3) is a blood tumor marker value reported on some lab panels. A CA 15-3 blood test shows the numeric amount of this marker in the sample, which is compared with the CA 15-3 normal range on the lab report. CA 15-3 results on a lab report can shift with body chemistry, hydration, testing context, and lab method, so the CA 15-3 reference range is used to put each value in context. Trends across repeated CA 15-3 test results are often more useful than a single reading.

Neuron-Specific Enolase (NSE) is a lab value that measures the amount of NSE, an enzyme found in neurons and some other body cells, in blood. On a Neuron-Specific Enolase blood test, the result helps describe how much of this marker is circulating and how it compares with the Neuron-Specific Enolase normal range.
