Fasting is generally recommended for the 5 ovarian tumor markers. The five ovarian tumor markers mainly include CA12-5, CEA, CA19-9, AFP, HE4. These tests require blood collection, and although they are not as affected by diet as biochemical tests, fasting is still recommended. If several blood markers are checked at the same time, such as liver and kidney function, blood cell analysis, etc., fasting for more than 10 hours is generally recommended. The 5 ovarian tumor markers are widely used in the clinic for the differential diagnosis of pelvic masses, monitoring the progress of the disease after treatment and judging the prognosis, especially for the monitoring of the efficacy of the treatment, which is quite sensitive. After the examination, you should also go to the hospital regularly for review, which can play a role in early prevention and early detection and treatment.
