A contaminated urine sample is where the urine sample cannot be analysed due to it being mixed or contaminated with bacteria other than from the bladder (e.g. from the urethra, unsterile sample containers etc). Contamination is not the same but can lead to what is called a false positive or a false negative sample. The reason for this is that if the sample is contaminated the doctor cannot tell what is wrong and will make a judgement call believing that there is an infection (i.e.

Because home pregnancy tests detect hCG, it is best to collect urine samples containing the highest presence of the hCG hormone. Diluted samples (from drinking high volumes of water / frequent urination) are not recommended and can diminish test accuracy. Instead, first morning urine is considered the ideal sample as it contains the most concentrated presence of hCG. Otherwise, waiting several hours (4-5 minimum) is also considered sufficient duration for an HPT. See similar questions...

You will need a special collection kit to perform the urine metals test. The metals test requires at least 40 mls of urine. See similar questions...

When ready for use drug free urine samples may brought up to acceptance temperature simply by running under hot water until the temperature strip displays between 90-99 degrees Fahrenheit. After thawing and achieving proper temperature make sure to shake the sample well so that any present particles dissolve completely. The samples should be thawed at a slow and constant rate so as to hinder crystals from precipitating. See similar questions...

Food such as raw poultry, raw meat and unwashed root vegetables may be contaminated with harmful bacteria.

For cats, place wide wax paper strips in the litter box. After the cat has urinated, pour off the urine. The best way to hold your new puppy is to place one hand under the hind end and support the chest with the other hand. This gives your pet a sense of security. See similar questions...

Formation of detectable crystalluria is dependent on the temperature, the pH, urine concentration, diet, metabolic abnormalities, drugs, and specimen handling. Some of these factors may be quite variable (ex. the postprandial alkaline tide may result in altered urine pH compared to a fasting sample, changing the diet and/or changing the pH in the sample may alter the type of crystal seen).
