Rheumatoid factor interference in the determination of carbohydrate antigen 19-9 (CA 19-9).
BACKGROUND Investigation of a 61-year-old Caucasian male suffering from fatigue and weight loss led to the finding of a carbohydrate antigen 19-9 (CA 19-9) concentration of 80 kU/L using an ADVIA Centaur analyser. Determination of CA 19-9 on Vidas, AxSYM and Architect i2000 systems gave normal results. His rheumatoid factor concentration was very high (900 kIU/L) and assay interference was susp...
متن کاملBenign Hydronephrosis and Elevated of Serum Levels of Carbohydrate Antigen CA 19-9: A Case Report
BACKGROUND Carbohydrate tumor-associated antigen (CA 19-9) has been shown to be upregulated in other malignant tumors including gastric, ovarian, hepatocellular, and colorectal carcinoma as well as benign diseases of the biliary track such as pancreatitis, cholangitis, and choledocholithiasis. According to the available literature, in several cases of benign hydronephrosis and in a few cases of...
متن کاملPancreatic Cancer with Normal CA 19-9 and Lewis Antigen Negative—Case Report
Pancreatic cancer is an aggressive and lethal disease that affects especially older population. Its more relevant tumor marker is CA 19-9 (carbohydrate antigen 19-9), although it can be elevated in others clinical situations, like cholangitis and cholestasis. Otherwise, a small people subset, like our patient, do not produce this tumor marker, as on blood as in the tumor, because they are incap...
متن کاملConcentrations of trypsin, elastase and carbohydrate antigen CA 19-9 in serum of cystic fibrosis patients.
CLINICALCHEMISTRY, Vol. 32, No. 5, 1986 913 with either substrate, but the observed activity was 55.7% lower with iralanine-4-nitroanilide, in contrast with what happens in sera of males and nonpregnant women. Evidently, i..-alanine-4-mtroanilide behaves like LCHA in this regard, probably reflecting the relative resistance of these substrates to the action of cystyl-aminopeptidase and perhaps o...
متن کاملAssociation between carcinoembryonic antigen, carbohydrate antigen 19-9 and body mass index in colorectal cancer patients
Carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) have been well recognized as tumor markers for colorectal cancer. Previous studies suggested that obesity is inversely associated with the screening of CEA and CA19-9 levels and may reduce screening sensitivity. This study was conducted to evaluate the association of body mass index (BMI) with serum CEA and CA19-9 concentrati...
