hi, i am 34 years old. i had a occult blood test for colorectal cancer screening because of family history. 3 samples were taken in 3 different days. the first and third samples were weakly positive . but the second sample was positive (+2). one day before the second sample i eat tomato and carrots.... also i take omeprazol before second sample. could i trust to the result of this test?? or is it necessary to repeat the test?? the CEA (antigen) test could help to the diagnostic process?
for screening purposes colonoscopy is best. now a days Circulating tumour cells tests have come up.but you should go with colonoscopy first. CEA is not good for screening as it can be raised in many other conditions also
