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 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 کاملDevelopment of a Sensitive Quantitative Competitive PCR Assay for Detection of Human Cytomegalovirus DNA
Accurate and rapid diagnosis of human cytomegalovirus (HCMV) disease in immunocompromised patients has remained as a challenge. Quantitative competitive PCR (QC-PCR) methods for detection of HCMV in these individuals have improved the positive and negative predictive values of PCR for diagnosis of HCMV disease. In this study we used QC-PCR assay, using a co-amplified DNA standard, to quantitate...
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 کاملUnusually Elevated CA 19-9 in Choledocholithiasis
12 mg/ dl, Carcinoembryonic antigen (CEA) 3.2 ng/ ml and a CA 19-9 of 38310 U/ml. Ultrasonographic examination and computed tomography of the abdomen were of poor quality due to body habitus. Magnetic resonance imaging (MRI) of the abdomen showed intrahepatic biliary dilatation, a dilated common bile duct of 11mm and no pancreatic mass. Endoscopic ultrasound revealed cholelithiasis as well as a...
