The examinations all consist of two three-hour papers, each containing 100 best-of-five questions, administered by computer at a local test centre.
Any difference in the results of a local test offered by the I.S.P. and an independent test could indicate whether the service provider or Internet at large is responsible for the delay.
Only 16 of 24 samples positive by local testing were confirmed by central testing (PPV = 67%%), although 132 of 134 samples negative by local testing were negative by central testing (NPV = 99 %).
Among the CTCs from patients with breast cancers clinically defined as HER2 positive from analyses of their primary tumours (FISH+ and/or IHC 3+ by local testing, n=24), 72% of all captured cells had a HER2 gene copy number ⩾4.
ER, PR, and HER2 status was determined by local testing.
In this study that evaluated a large number of samples, we found a discordance rate of 4.0%; 22 of 552 unique tumor samples initially found to be HER2-negative by local testing were determined to be HER2-positive upon central retesting.
To investigate the reliability of a combined strategy of clinical assessment score followed by a local D-dimer test to exclude deep vein thrombosis.
The correct choice was guided both by room location and by local test box cues (i.e., cup A was reinforced in box context 1 + place 1 and cup B was reinforced in box context 2 + place 2).
Only three eyes that had confirmed progression by local test point condensation demonstrated a non-progressive visual field at some time after confirming progression.
Since some genes contain many more variants than others, we control the false positive rate in local testing by retaining only associations that meet a Bonferroni-corrected significance cutoff of 0.05.
