Description of Blood Analysis: 

Glycoprotein marker CA-72.4 is a specific antigen associated with the epithelial cells of the gastric and ovarian mucosa. Under normal conditions, this compound rarely enters the systemic circulation. A rise in its concentration serves as a biochemical signal of cellular metabolism transformation or a disruption in natural tissue regeneration. In clinical diagnostics, CA-72.4 is used not as a standalone diagnostic tool, but as an indicator of biological stability, helping the physician track changes in response to therapy or internal factors.

What does the analysis represent?

• Purpose: Quantitative determination of CA-72.4 antigen concentration in blood plasma.
• Primary Application: Systematic monitoring of GI tract and pelvic organ tissues, evaluating the effectiveness of the chosen treatment strategy.
• Method: Highly sensitive immunochemical study of a venous blood sample.

Recommendations for the Test (General)

• Timing: The procedure should ideally be scheduled for the morning.
• Fasting: A food intake pause of 4 to 6 hours is necessary.
• Rest: It is important to spend at least 20 minutes in a calm, seated position before the blood draw.
• Recommendations: It is advisable to perform the test outside the acute phase of infectious diseases.

What can affect the results?

• Factors increasing levels: Benign ovarian diseases, liver cirrhosis, and chronic inflammatory processes in the abdominal cavity.
• Influencing factors: Individual metabolic rate and the recovery stage following recent abdominal surgeries.

When to take the test?

• Recommendations: Ordered by a specialist to monitor the activity of previously identified changes or during a comprehensive evaluation of the digestive system.
• Preparation: Optimally taken when no acute inflammation is present, unless otherwise directed by a physician.

How to interpret the results? 

Numerical data analysis is a task for a medical professional. The CA-72.4 value is never viewed as an isolated verdict. The specialist analyzes this indicator in close connection with patient complaints, gastroscopy (EGD) results, and Ultrasound or CT data. Self-interpretation is prohibited, as deviations may be caused by benign factors that only an expert can properly weigh.

Possible further investigations

• Endoscopy: Gastroscopy (EGD) for detailed inspection of the stomach lining.
• Visualization: Pelvic ultrasound, CT, or MRI of the abdomen to clarify the localization of changes.
• Associated Markers: Simultaneous testing of CEA or CA-19.9 for a complete diagnostic profile.

When does the next step make sense? 

If CA 72.4 levels are checked to monitor the stomach or ovaries, results are assessed holistically with the clinical picture. The necessity of further testing is determined by the specialist after analyzing the entire data set. 

👉 If necessary, you can discuss the analysis results with a specialist such as a oncologist ( Doctors – TAMC).
