Comparison of seven immunoassays for the quantification of CA 125 antigen in serum.
Seven CA 125 immunoassays were compared for their clinical performance. CA 125 concentrations were determined in 289 serum samples obtained from women with benign pelvic tumors (samples from 98 patients) and patients with various cancers (samples from 111 patients). In the range of 0-1000 kilounits/L, all assays tested were linearly correlated, with correlation coefficients ranging from 0.89 to...
متن کاملAnalytical and clinical performance of improved Abbott IMx CA 125 assay: comparison with Abbott CA 125 RIA.
We compared the improved Abbott IMx cancer antigen (CA) 125 assay (cat. no. 7A89) with the Abbott CA 125 RIA. Serum specimens were from healthy perimenopausal women (n = 124) and from patients with benign gynecologic and nongynecologic diseases (n = 124), ovarian carcinoma (n = 104), or other malignancies (n = 193). The IMx assay detected as little as 0.193 kAU/L CA 125 (AU = arbitrary Abbott u...

متن کاملClinical evaluation of the Byk LIA-mat CA125 II assay: discussion of a reference value.
The Byk LIA-mat CA125 II assay was compared with the Centocor IRMA CA125 II. Serum samples studied (n = 1012) were obtained from 652 apparently healthy females, 61 pregnant women, and 299 patients with benign and malignant gynecological tumors. The CA125 II assay value at the 95th percentile of the total healthy group was 29 kU/L for the LIA-mat and 32 kU/L for the Centocor assay. For the LIA-m...
متن کاملFrequency Improves on MinImum
Various authors (1,2) have tried to ascertain whether CA 125 concentrations in PF samples were significantly higher in patients with endometriosis than in control subjects. So far, these studies have not shown any significant difference in CA 125 values obtained from undiluted PF samples. In our study, using diluted samples in one-step assay, we found that CA 125 concentrations differed between...
