Who considers Urine for Extended Culture
- People often consider these tests if they have a spreading rash or flu-like illness after a tick bite.
- A cough lasting more than three weeks, night sweats or weight loss may prompt TB testing, as may pre-employment or visa requirements.
- Persistent indigestion or stomach pain commonly leads to Helicobacter pylori testing.
- Those who work with birds, soil or in farming sometimes check for organism-specific antibodies or precipitins.
- Pregnant women may be offered Group B streptococcus swabs late in pregnancy.
What Urine for Extended Culture measures
The catalogue tags the Urine for Extended Culture with urinalysis, urinary Tract Infection and bladder Infection. Those terms describe the territory the test covers; the notes below explain what a bacterial, parasitic and fungal infections result can and cannot tell you.
This group covers tests that identify infections other than viruses: antibodies to bacteria such as Borrelia (Lyme disease), Mycoplasma pneumoniae, Brucella, Legionella and Helicobacter pylori; PCR and culture that detect the organism directly, including TB, whooping cough, Group B streptococcus and MRSA; and antibody or antigen tests for parasites and fungi such as Toxoplasma, Strongyloides, Aspergillus and Candida. Interferon-gamma release assays (TB Quantiferon) measure the immune response to tuberculosis rather than the bacterium itself. Precipitin tests look for immune reactions to inhaled organic dusts.
Preparing for your Urine for Extended Culture
- 1No fasting is needed for most tests, but Helicobacter pylori stool antigen requires two weeks off acid-suppressing tablets and four weeks off antibiotics.
- 2Antibody tests for Lyme disease are often negative in the first few weeks; a sample four to six weeks after the bite is more informative.
- 3Follow the specific collection instructions for swabs, sputum or stool, which the nurse will explain.
Sample for this test: mid-stream urine sample.
Understanding your Urine for Extended Culture results
A positive antibody result can indicate current or past infection depending on the class of antibody and the organism; for Lyme disease a positive screen is confirmed by immunoblot before conclusions are drawn. Culture and PCR results identify the organism and, for culture, its antibiotic sensitivities, which helps guide treatment. A positive TB Quantiferon shows exposure to tuberculosis at some point and needs clinical assessment and a chest X-ray to distinguish latent from active infection.
Infection tests are interpreted alongside the timing of exposure, symptoms and examination; a negative result early in an illness does not exclude infection.
