- Hemolyzed or lipemic samples
- Improperly labeled or insufficient sample volume
- Samples not stored as per stability guidelines
Understanding Your Results
Likely no active ovarian cancer, but does not rule it out entirely.
Level: Normal (<35 U/mL)
May indicate ovarian cancer, but further testing is needed to confirm due to possible benign causes.
Level: Elevated (≥35 U/mL)
Could suggest cancer progression or recurrence; monitor with additional tests.
Level: Rising levels
May indicate positive response to treatment in diagnosed cases.
Level: Falling levels
Consult a doctor if you experience persistent symptoms of ovarian cancer, such as abdominal bloating or pelvic pain, or if CA 125 test results are elevated. Also, seek advice if undergoing ovarian cancer treatment for monitoring.
Limitations
