The line to get tested for wrapped around the corner of 2nd and King Streets in San Francisco Tuesday afternoon. For Juliano and Renata Correia, it doesn't matter what kind of test they get – they just need a test. "We are returning to Brazil tomorrow and we must be tested before goi...
eight to 10 hours. Sameday Health, also based in New York, guarantees a PCR test result in one hour for $250. For a fee of $400, My Doctor Medical Group, a private practice in San Francisco, says it will deliver a PCR test result by 9 a.m. the day after the test is ...

1. The detection flux of the instrument The first thing to consider is how often the laboratory needs to use a quantitative PCR instrument. David Ginzinger, head of genome analysis equipment at the University of California, San Francisco Cancer Center, has tested most of the quantitative PCR ma...
Comparability of MRD results by RQ-PCR and NGS was assessed using bivariate correlations between methods analysis (software R 3.0.1 with cor.test). Results Sanger sequencing of multiplex PCR detected 60 clonal IGH, IGK, TRB, TRG and/or TRD gene rearrangements at diagnosis (1-6/patient), ...
The current ‘gold standard’ for the identification of M. tuberculosis in clinical specimens is based on acid-fast microscopy of sputum Sediments or other specimens (AFB smears), followed by culture confirmation using definitive biochemical or DNA probe
High concentrations of protein and cellular DNA present in test samples have been demonstrated to have no impact on X-MuLV quantification. The X-MuLV clearance during chromatography and filtration procedures determined by this method is highly comparable with that determined by the cell-based ...
In the ITS1 region, the propor- tions of ascomycetes and basidiomycetes were quite simi- lar across the size range (p = 0.2, two tailed T-test), but 'non-dikarya' fungi had far more short fragments and dif- fered significantly from the two other groups (p < 0.01 and p < ...
Quantification of unknown sample by dPCR. Digital PCR was quantified on the BioMark System (Fluidigm, San Francisco, CA) using 37 K qdPCR (48 × 770) integrated IFC controller (Fluidigm, San Francisco, CA). Three different vials from each level of unknown sample, labeled as A1...
