For those with access to Medscape, a great article on Urinalysis and Pregnancy. Of specific notation, did you know that studies show that doing a "clean catch" is clinically NOT NECESSARY as results indicate no difference in the positive culture rates between those who did a clean catch and those that did not:



"The 'midstream clean-catch' urine sample is currently the standard collection method.[...6] It is thought to decrease sample contamination and false-positive results, especially when the specimen is used to determine the presence of infection.[1,2] With this method of sample collection, the patient is instructed to cleanse the labia and urethral meatus prior to voiding and to commence collection of the sample midway through voiding. Bradbury collected urine samples from 316 women, 158 of which had symptoms suggestive of a urinary tract infection (UTI) and 158 controls. All subjects were randomly assigned to one of two collection methods, involving either preparatory vulvar cleansing or not. There was no difference found in positive culture rates between the two groups (24.7 and 24.6%, respectively, in the symptomatic group and 2.4 and 1.4%, respectively, among controls). There was also no difference in rates of sample contamination, as indicated by the presence of epithelial cells.[7] In a more recent study, Lifshitz and Kramer collected 242 consecutive urine samples from women randomized into three collection technique groups. The first group was told to simply urinate into a clean container, the second group was given the standard clean-catch midstream instructions, and the third group was given the same instructions as the second group with the addition of a vaginal tampon. Contamination rates were calculated for all three groups and no differences were found (29, 32 and 31%, respectively; p = 0.82).[6] This suggests that details of the collection method do not make a difference in the detection of a UTI."
