A SENSITIVE AND RAPID NITRITE-TEST

 

DESCRIPTION: NITRISTIC® is an notably sensitive and rapid test for showing bacterial reduction of nitrate to nitrite in fluids. It is mainly used for testing urine - a positive test indicates a urinary tract infection due to the growth of nitrate-reducing (nitrite-producing) bacteria (the most common cause of such infections) in the urinary bladder
REMARKS: N.B. Occasionally symptoms from the urinary tract are due to a non-bacterial inflammation or to an infection by a bacterium unable to reduce nitrate, e.g. Staph. saprophyticus or streptococcus - in such cases nitrite tests will of course be negative. To check this out your physician may prescribe a bacteriological culture. In other cases a negative nitrite-test could be due to insufficient bladder-incubation time (frequent urination) or to inadequate dietary nitrates in the urine. Test again at different times of the day.
PROCEDURE: Dip the stick's paper-end momentarily in a freshly voided urine specimen or urinate directly upon it. Read immediately - any pink tone is positive. Discoloration which may develop after a few minutes is insignificant so you may dispose of the stick immediately after inspection.
- If your urine tests positive, you are advised to inform your physician, even if you are free from symptoms - you may have a urinary tract infection in need of treatment or further control.
OTHER USES: - If your aquarium water tests positive, it probably contains potentially harmful bacteria and should be replaced.
- If your drinking water tests positive, it is presumably contaminated and could be dangerous even after boiling - especially hazardous for infants (risk for potentially fatal methemoglobinemia).
- If your swimming pool water tests positive, it is probably grossly polluted with intestinal bacteria. Change the water and check out your purification system.
REACTION TIME: One to ten seconds - depending on concentration of nitrite.
REACTION COLOR: All pink tones = positive (no need for an interpretation chart or scanner) - see table below.
SENSITIVITY: Reacts at less than 1 micromole nitrite/liter.
SIZE: 80 x 9 mm.
REACTIVE SURFACE: 15 x 5 mm.
DURABILITY: At least 2 years in unopened package.
STORAGE: Normal room temperature.
