PresentationAppropriate Tests

Urine microscopy and culture.

For first infections in women, urine microscopy and culture may not always be necessary before antibiotic treatment is commenced. If a urine sample is turbid and urinalysis reveals a positive leucocyte esterase test with or without a positive nitrite test, infection can be diagnosed presumptively.

When urinary tract infection is suspected in males, young girls or women with a history of previous infection, urine microscopy and culture should be done.

Urine may be collected as a midstream specimen, by needling an indwelling catheter or by suprapubic aspiration (children).

Urinary tract obstruction including prostatic enlargement can be a predisposing factor.
