13. Direct Sensitivity Test of the MB/BacT System
In order to evaluate the direct-method test of sensitivity to drugs used in the principal tuberculosis treatment regimes, in the Organon Teknika MB/BacT system, we tested 50 sputum samples positive to microscopy taken from patients with pulmonary tuberculosis and with clinical indications for an antibiogram, admitted sequentially for examination during the r

14. Avaliação de ensaio molecular para determinação de carga viral em indivíduos sorologicamente negativos para o HIV-1
O teste de carga viral foi concebido para acompanhar a evolução e o tratamento do paciente com diagnóstico confirmado de HIV-1. Contudo, sua especificidade diagnóstica não foi ainda avaliada em pessoas que apresentam um teste sorológico negativo. Mesmo assim, ele tem sido erroneamente utilizado para o diagnóstico da infecção primária pelo HIV-1. Es

16. Comparative evaluation of commercial enzyme immunoassay kits for detection of hepatitis B seromarkers.
The commercial hepatitis B enzyme immunoassay kits of Abbott Laboratories and Organon Teknika were compared for their sensitivity, specificity, and reproducibility in detecting the hepatitis B seromarkers hepatitis B surface and e antigens and antibodies to hepatitis B core, e, and surface antigens. With the exception of the Organon kit for antibodies to hep

17. Evaluation of five hepatitis delta virus marker assays for detection of antigen and antibody.
Five commercially available assays for hepatitis delta (HD) virus markers were compared for sensitivity, specificity, and reproducibility: three assays for antibody (anti-HD), provided by Diagnostics Pasteur, Organon Teknika, and Abbott Laboratories, and two assays for antigen (HD Ag), from Pasteur and Organon Teknika. The assay from Organon Teknika is the l

18. Comparison of Roche MONITOR and Organon Teknika NucliSens Assays To Quantify Human Immunodeficiency Virus Type 1 RNA in Cerebrospinal Fluid
We compared Roche MONITOR and Organon Teknika NucliSens assays for human immunodeficiency virus type 1 (HIV-1) RNA in cerebrospinal fluid (CSF). Results of 282 assays were highly correlated (r = 0.826), with MONITOR values being 0.29 ± 0.4 log10 copies/ml (mean ± standard deviation) values. Both assays can reliably quantify HIV-1 RNA in CSF.

19. Kinetics of delta antigen and delta antibody in acute delta hepatitis: evaluation with different enzyme immunoassays.
The kinetics of delta antigen (HDAg) and anti-delta antibody (anti-HD) was analyzed in 22 acute delta hepatitis infections (11 coinfections and 11 superinfections), with an enzyme immunoassay developed by Organon Teknika and with two commercially available assays: Deltassay, a test for HDAg from Noctech and Abbott anti-delta enzyme immunoassay, a test for an

20. Evaluation of a sustained-release oral tetracycline in non-specific urethritis.
A double-blind trial of oxytetracycline (Imperacin-I.C.I.) and tetracycline hydrochloride in a sustained-release formulation (Tetrabid-Organon) was carried out on 259 men suffering from non-specific urethritis. Patients who had NSU in the preceeding 3 months were excluded from the trial. The response to treatment assessed at 10 days was favourable in ninety

21. Report of a joint DMRQC/Organon field trial to detect hepatitis A IgM by ELISA.
The results of a field trial of a joint DMRQC/Organon ELISA kit for the detection of hepatitis A IgM antibody are reported. The participating laboratories were asked to use the kit to test a panel of 360 specimens consisting of duplicate coded samples of 180 sera. The panel was also tested by MACRIA in the Virus Reference Laboratory, Colindale. The ELISA was

23. Comparison of relative uses of commercial assays for Toxoplasma gondii IgM antibodies.
AIMS: To compare the sensitivity and user friendliness of seven commercially available enzyme linked immunoabsorbent assay (ELISA) kits for toxoplasma specific IgM. METHODS: Five antibody capture assays supplied by Abbott, Mercia, Northumbria, Organon and Sorin, and two indirect ELISA assays from Biostat and Mast, were assessed. Using defined dilutions of To

24. Conventional and Molecular Methods for Verification of Results Obtained with BacT/Alert Nonvent Blood Culture Bottles
A strategy comparing molecular and conventional methods for verification of the BacT/Alert nonvent blood culture bottles (Organon Teknika, Durham, N.C.) was performed with seeded isolates. The bottles were evaluated with 12 common organisms from bloodstream infections. Overall, the bottles were equivalent as determined by conventional and molecular methods.
