CA 72-4
CA 72-4 is a glycoprotein tumor marker found in the blood. This test is primarily used to monitor gastric (stomach) cancer and ovarian mucinous carcinoma.
Category: Tumor Markers
Also known as: ca 72-4, ca72-4, ca 72 4, cancer antigen 72-4
Reference range: 0–6.9 U/mL (Source: ABIM)
Standard unit: U/mL
High values may indicate
High CA 72-4 levels may indicate gastric cancer, ovarian cancer, colorectal cancer, pancreatic cancer, or non-cancerous conditions such as pancreatitis or liver cirrhosis.
Low values may indicate
Low CA 72-4 levels are normal and may indicate a good response to cancer treatment in patients being monitored.
Frequently asked questions
- What is a normal CA 72-4 level?
- A typical reference range for CA 72-4 is 0–6.9 U/mL (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is CA 72-4 measured in?
- CA 72-4 is most commonly reported in U/mL. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do CA 72-4 reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track CA 72-4 over time?
- Yes. Upload results from any lab and BloodId charts your CA 72-4 over time against its reference range, so you can see whether the trend is rising, falling, or stable.
