test pads tend to be more sensitive to free hemoglobin than to intact red cells.
patent (5) has recently been granted for such a device whereby the control fluid is contained within a thermoplastic pouch that allows for the full immersion of a urinalysis dipstick
in only 1.
7% of platelet concentrates had 4+ and 3+ of glucose with dipstick
The leucocyte esterase dipstick
test was positive in 11 culture-positive cases, whereas the nitrite dipstick
test was positive in 33 culture-positive cases (Table 2).
Using ELISA as the gold standard, the microscopic analysis had a slightly higher specificity and positive predictive value (PPV), indicating greater confidence in positive test results relative to the dipstick
method (Table 2).
In 2 mixed G1-G9 infections, G9, but not G1 RNA, was recovered, and G1 RNA was recovered from dipstick
RNA in addition to G9 from a G9-infected child.
The results of the study in cats showed that when both the urine dipstick
and SSA test results were in the trace to 1+ range, the positive results are best confirmed with a more specific-specific ELISA assay.
Analyz= ing chemical and physical properties, the dipstick
outputs its data to a ha= nd-held device or computer.
The bioactive dipstick
is immersed in a solution containing the test analyte (a substrate for the enzyme) and a Au(III) salt.
Police in north Staffordshire are using dipsticks
to test the contents of youngsters' beverages in a bid to combat under age drinking.
Not surprisingly, the risk of ESRD was especially high when both the dipstick
test and eGFR were abnormal - 41 times higher than in men with normal results on both tests.
results depend on protein concentrations, which are altered by urine volume.
