All methods employing paper reagent strips
are subject to an intrinsic haematocrit bias; the higher the haematocrit value, the lower the result.
Participants identified a total of 20 514 QC events that should have occurred (per institutional regulations) for glucose and urine reagent strip
testing, with an average of 195 QC events per institution.
The suctioned tracheal secretions were inspected visually for blood before being taken to a research laboratory where the glucose concentration was measured by an automated glucose analyzer and glucose oxidase reagent strips
The review of the literature suggested that refractometer and reagent strip
values were closely related.
At a level 2 cutoff, reagent strips
gave an 89% specificity, 74% positive predictive value, and 99% negative predictive value.
use the principle of protein error of pH indicators to detect protein (1, 2).

Hemastix Reagent Strips
use 3,3',5,5'-tetramethylbenzidine and diisopropylbenzene dihydroperoxide.
Duplicate 1-mL samples of urine containing blood concentrations giving reagent strip
values of 0, trace, 25, 80, and 200 were then set up and analyzed for thiocyanate using the standard reaction conditions.
The AvoSure PT Systems provide a simple and accurate Prothrombin Time (PT) test by means of a small, hand-held electronic meter that reads a disposable reagent strip
A If a physician has specifically requested a test for urine eosinophils, I do not think it would be correct to screen specimens with a reagent strip
test for leukocyte esterase as a criterion for canceling a Hansel's stain for eosinophils in the urine.
The AvocetPT-Pro, is a simple and accurate Prothrombin Time (PT) test consisting of a small, hand-held electronic meter that reads a disposable reagent strip
