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 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...
متن کاملMeasurement of serum carcinoembryonic antigen, carbohydrate antigen 19-9, cytokeratin-19 fragment and matrix metalloproteinase-7 for detecting cholangiocarcinoma: a preliminary case-control study.
Cholangiocarcinoma is a malignant tumor of the liver arising from the bile duct epithelium, accounting for 10-25% of all primary hepatic cancers. The clinical presentation of this tumor is not specific and the diagnosis of early cholangiocarcinoma is difficult, especially in patients with other biliary diseases. Measurement of serum carbohydrate antigen (CA) 19-9 and carcinoembryonic antigen (C...
متن کاملValidity of carcinoembryonic antigen and carbohydrate antigen 19-9 measurements in pancreatic cyst fluid with a serum-based immunoassay.
Imaging techniques, cytology, and biochemical analysis [including carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA 19-9) concentrations] of pancreatic cyst fluid obtained by endoscopic ultrasound-guided fineneedle aspiration are used to differentiate pancreatic cyst lesions, particularly those with malignant potential (1, 2 ). American College of Gastroenterology guidelines have...
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...
