When used properly, the AZO® Test Strips home UTI test can detect that you may have a urinary tract infection (UTI). AZO® Test Strips test for both leukocytes (white blood cells or WBC's) and nitrite. These tests performed together are more effective for detecting a UTI than testing for nitrite alone.

Phenazopyridine Hcl is an azo dye that works as a topical pain reliever. When you take an over-the-counter medication that contains it, the drug enters the lower urinary tract and temporarily desensitizes the area. This alleviates the burning, pressure, and urgency symptoms of a UTI.

AZO® Test Strips can help detect if you have a UTI with quick results that you can share with your doctor. With AZO® Test Strips you get: Accurate test results –the same test most doctors use to diagnose a UTI. Quick results in just two minutes.

The test works by measuring both Leukocytes and Nitrites. This is the same method used by many doctors, giving you equally reliable results. NITRITE - Certain bacteria change nitrate to nitrite in your urine. These bacteria can often cause a UTI, which is why they can be a strong indicator.

The azo dye test determines whether an organic compound contains a primary aromatic amine or not. The main reagents for the azo dye test are sodium nitrate, hydrochloric acid, and beta-naphthol.

In the meantime we're going to go ahead. And also test the second urine checking the strip. Looks good. So we'll go ahead and dip the second urine. And lay it.

AZO doesn't cure a UTI, but it can make you feel more comfortable while you're waiting for an antibiotic to start working. While you're taking AZO, it can turn your urine an orange-red color that can stain clothing.

The urine test strip reaction is based on the action of leukocyte esterase in catalysing the hydrolysis of an ester of indolecarboxylic acid. The indoxyl that is liberated combines with a diazonium salt in order to produce a violet coloured azole dye. The esterase reaction needs about 2 minutes to take place.

A urine reagent strip (dipstick) is a firm plastic strip to which pads saturated with chemicals are affixed. The chemicals in the pads indicate the presence of specific substances in the urine. The strips may also indicate the pH and specific gravity of the urine, depending on the type of strip that is used.

Azo dye properties Their biggest advantage it their cost-effectiveness, which is due to the processes involved in manufacture. The general formula for making an azo dye requires two organic compounds- a coupling component and a diazo component.

Methyl red is an azo dye, or a synthetic dye, which is one of the common chemical indicators used in the laboratory to determine pH transitions within a specific range. It's most effective between pH 4.4 and pH 6.2. If the pH level is below 4.4, its colour is red, and if it's above 6.2, the colour turns yellow.

The main reagents for the azo dye test are sodium nitrate, hydrochloric acid, and beta-naphthol. In the azo dye test, a primary aromatic amine reacts with nitrous acid, which is generated in situ by the reaction of sodium nitrite with hydrochloric acid (HCl) at 0–5°C to produce a diazonium salt.

Azo Test Strips Dosage and Administration Match color of each test pad to color chart for that test. Nitrite test: any amount of uniform pink color is positive. Leukocyte test: a positive test will give a dark tan to purple color.

Phenazopyridine is available under the following different brand names: Azo Standard, Pyridium, Prodium, Pyridiate, Baridium, Uricalm, Urodine, and UTI Relief.
