Why It Is Done

How To Use UTI Test Strips – Are Urinalysis Test Strips Accurate?

A home test for urinary tract infection may be done to:

  • Find a UTI, especially in people who have UTIs often.
  • Check how well treatment of a UTI is working. If you are being treated for a UTI, you can test your urine at home to see if the antibiotics have cured the infection.
  • Test young children who have frequent bladder infections but may not be able to report their symptoms. A home test for these children is done under a doctor’s care.

Diagnostic Tests Confirm Diagnose In The Patients With Symptoms

A diagnostic test diagnoses people who are very likely to have the disease because they have common symptoms.

For example, a diagnostic test is perfect for a woman who has some classic symptoms of a UTI: goes to the bathroom 15 times a day, and has pain with urination. She could use an OTC UTI test strip, but the result will be less accurate.

OTC UTI test strip does not rule in disease. For that, you need a diagnostic test. Diagnostic tests are specific, if they are negative, you can be sure you dont have the disease.

So if you already have UTI-like symptoms, you want to rule all other reasons before starting a treatment for UTI. For example, if you think you have a UTI when in fact you have a kidney stone, you waste precious time and resources taking antibiotics or herbal remedies that will do nothing to get rid of the stone. Diagnostic tests shine at weeding out all the people who are likely to have a disease but dont.

What Does The Test Measure

At-home UTI tests use urine dipsticks that check for two substances in the urine: leukocytes and nitrites.

  • Leukocytes: Leukocytes are a type of white blood cell . Tests may assess WBC levels by measuring an enzyme called leukocyte esterase that is released by WBCs when they are present in the urine. Detecting leukocyte esterase in the urine is a sign of inflammation that is most often related to a urinary tract infection.
  • Nitrites: Nitrites are substances that may be created in the urine when significant numbers of bacteria enter the urinary tract. Although most bacteria that cause UTIs produce nitrites in the urine, some less common microbes do not.

While finding these substances in the urine suggests a UTI in certain patients, testing for them may be misleading in people without symptoms. This is because leukocytes and nitrites may be present in the urine of people without a UTI or in people with other conditions.

Lets Start With A Symptom Check

Not everyone with a urinary tract infection develops symptoms, but most have at least a few tell-tale signs.

Do any of these apply to you?

  • You experience a burning sensation when you urinate.
  • You feel a strong, persistent need to urinate, yet only pass a small amount.
  • Your urine is cloudy or contains blood.
  • Your urine has a strong odor.
  • You have pain in your back or lower abdomen.
  • You experience nausea, vomiting and/or just feel ill.

Two or more? Time to see your doctor. And the sooner you get UTI treatment, the better. UTIs are no joke left untreated the infection could lead to serious complications.

Why Are Urine Cultures Important During Pregnancy

If you are pregnant, your obstetrician may have you do a urine culture at several points during your prenatal care as a precautionary measure. If you have developed a UTI during your pregnancy, its essential to catch it and treat it. UTIs are common in pregnancy and can, at times, go unnoticed. Untreated UTIs can lead to premature labor or poor labor outcomes.

Is My Otc Uti Test Same As The One Used By A Doctor

No, its not.

Despite the claims of over-the-counter UTI testing strip companies, it is not the same test your doctor uses. Rather it is a truncated version of your doctors test, that ignores important information about your urine.

For example, the urine test your doctor uses checks for more evidence of urine infection. It looks at the important factors that increase the sensitivity of the test and may suggest other reasons for your urinary symptoms:

  • Your urine pH
  • Blood in the urine

Collecting Urine Samples And Dipstick Testing

The recruiting clinician will attempt to obtain a urine sample from the children of consenting parents during the recruitment visit. If this is not possible, the recruiting clinician will ask the parent to collect the sample at home, give them the appropriate equipment and explain how to collect it. To minimise contamination, urine samples will be obtained using the clean catch where this is possible. Where this is not possible, the nappy pad method will be used, as described by Liaw et al. and as recommended by the recent NICE guidelines . Urine sampling can be underway whilst the recruiting clinician completes the study CRF.

The recruiting clinician will retrieve the urine sample, test it with a urine dipstick provided by the study and record the urine sampling method and dipstick result on the CRF. The urine sample will then be split, if sufficient quantity is available, with the priority fraction being sent to the local NHS laboratory for routine diagnostic processing, and the second research fraction being sent to the SACU reference laboratory: for more in-depth analysis. As only small volumes of urine are required for each laboratory, it is expected that for most urine samples, it will be possible to split the urine into the two fractions.

Data Entry In The Local Nhs Laboratory And Central Research Laboratory

Once in the local NHS and SACU research laboratories, staff will be able to access an anonymised data collection page, where only study numbers and the data collection forms for the urine samples can be seen. Laboratory staff will be asked to log the samples on receipt and enter the results when available.

How The Uti Home Screening Test Works

Easy@Home Urinary Tract Infection Tests

The vH essentials UTI Home Test is a quick and simple test that detects urinary nitrite and the presence of protein in the urine. Subsequent to the application of urine, color differentiation determines whether the test is positive or negative. For example, a color change from white to pink and from yellow to green develops when nitrites and proteins are detected, respectively. A deeper color signifies higher concentrations of proteins and nitrites.

The accuracy of this test is limited by certain circumstances that may skew the results. For example, false-negative results may be observed following high consumption of ascorbic acid, antibiotics, or fruit juices, or if the urine is not in the bladder for at least 4 to 6 hours. False positives may present if the urine specimen appears red due to any cause for example, recent ingestion of common UTI pain relief medication containing phenazopyradine dye or contamination with menstrual fluid. In the event of a positive nitrite or protein result, patients should contact their primary health care provider. And even if both nitrites and proteins are negative, patients with persistent symptoms need to see a health care provider for further evaluation. Patient instructions may be found in TABLE 1.

Cultures And The Laboratory Diagnosis Of Utis

Routine bacterial urine cultures. Urine culture may not be necessary as part of the evaluation of outpatients with uncomplicated UTIs . However, urine cultures are necessary for outpatients who have recurrent UTIs, experience treatment failures, or have complicated UTIs. Urine cultures are also necessary for inpatients who develop UTIs. The bacterial culture remains an important test in the diagnosis of UTI, not only because it helps to document infection, but also because it is necessary for determination of the identity of the infecting microorganism and for antimicrobial susceptibility testing. This is particularly true because of the increased incidence of antimicrobial resistance.

Catheterized patients and many patients with infections of the lower urinary tract have colony counts much lower than 105 cfu/mL if the specimens are obtained via suprapubic aspirate or catheterization . Accordingly, the most appropriate diagnostic criterion for urine culture specimens obtained via suprapubic aspirate or catheterization is a bacterial concentration of 102 cfu/mL .

Interpreting culture results for urine specimens yielding common urinary tract pathogens.

What Do Uti Strip Colors Mean

There are several over-the-counter UTI dipstick tests available, and they work much like youd expect: Youre instructed to offer a clean-catch urine sample by holding the provided test strip in your urine stream for a few seconds. After a short wait, the color of the test strip changes to indicate the presence of a possible infection. To ensure the most accurate reading possible, use the test right after you wake up, with urine thats been in your bladder overnight.

While some OTC UTI tests screen for just nitrites , other tests analyze leukocytes , as well. And still others add a pH-level screener, too. This means that for many UTI tests, you will need to look at more than one test pad on a single strip and those results appear at varying times. For instance, your nitrite results may appear a full minute before leukocytes show. Once all results are in, youll need to closely compare the test pads with corresponding color blocks that appear on an included chart. You might notice, for example, that the nitrites box went from white to pink. That means nitrites have been detected, which suggests that you may have a UTI.

“I don’t know if they’re benefiting from treatment because they really have bacterial urethritis, or if they’re being exposed unnecessarily to antibiotics,” Donnenberg says.

OK, this is all very interesting, but how is it going to help a woman who thinks she probably has a UTI? Like, uh, right now?

Unfortunately, doctors don’t have a more accurate test to replace the urine culture.

As a result, doctors have become increasingly comfortable with prescribing antibiotics without doing a urine culture, Donnenberg says, and this study supports doing that for healthy female patients. “If their physician doesn’t do cultures, that should not make them uneasy.”

Going for a urine culture is often a good idea the first time a woman has UTI symptoms, Donnenberg says, to make sure the symptoms aren’t caused by the sexually transmitted diseases chlamydia or gonorrhea instead.

“But once a woman knows it’s a UTI because she’s had a few, calling up the doctor and saying, ‘I have another one, can I have a prescription?’ is fine.”

Are Urine Dipsticks Reliable

The literature supports that overtreatment of UTI is a knownproblem . A study showed that when doctors used only theurine dipstick test to diagnose classical lower urinary tractsymptoms, 47 per cent of the patients received unnecessaryantibiotics, while 11 per cent did not receive proper treatment. Most studies on urine dipsticks are, however, done onother population groups than the elderly. When we know thatthere is a high prevalence of both UTI and ASB in the elderlypopulation, and that it is important to distinguish between thetwo, it is interesting to study the reliability of urine dipsticktests for elderly patients. The research question for this studywas thus the following:

What Uti Test Should Children Have

A UTI diagnosis in a child requires both a urinalysis and a urine culture, according to the most recent clinical practice guidelines by the American Academy of Pediatrics. In order to gather a proper urinary sample from a very young child, catheterization or a suprapubic aspirate is often recommended. Alternatively, your healthcare provider may simply leave the child diaper-free in order to obtain a sample when the child urinates. Some physicians collect urine using a bag. Samples obtained in this way, however, have a high rate of contamination, making results unreliable.

For children who are potty trained, a midstream urine sample should be collected. Its often recommended that girls sit backward on the toilet, in order to widen the labia and prevent contamination.
