摘要
This paper compared various correlation of IMRA for CA19-9 and CA50 in the digestive system tumour antigen, such as linearity, sensitivity, analytical range, precision as well as storage and stability and so on. And it also determined serum level of CA19- 9 and CA50 of patients with different tumours. The results showed it was well correlated to CA19- 9 and CA50 as a marker of digestive system tumour. Particularly high levels of both markers were found in patients with pancreastic colonic cancer. Therefore it is possible to obtain a higher sensitivity and acceptable specificity by combination with CA19-9 and CA50.
