Can day old urine if kept in fridge over night and then brought upto the right tempiture will it pass?
Yes..it must be between 92-100 degrees fahrenheit when it is put into the specimen cup.
How soon must a urine specimen reach the laboratory?
How soon a specimen of something must reach the laboratory depends partly on the reason for which it is being sent to the laboratory, environmental conditions during storage and transit, and the stability of the substances the specimen consists of. A urine specimen must be refrigerated during storage and transit and arrive in the lab within an hour or two. It cannot sit out because warmth will allow bacteria, if present, to begin to grow in numbers.
Can an employer watch you give a urine specimen?
Yes, and in some cases it's required--some transportation workers must, and all military members must be observed.
Why is it important to take blood cultures with an aseptic technique?
A aseptic urine collection is important so they can have a clean-catch. A urine specimen is sometimes called a clean-catch, urine culture, or midstream specimen of urine, and is a method of collecting a quantity of urine for testing
Can an employer schedule you a sixth day with in a week without your consent?
they must give you at least a 24hour notice.
Can you keep clean urine in refrigerator and how long?
urine specimens should generally be processed as soon as the collection is complete. Some urine specimens ,such as urine for VMA, Cortisol, and other metabolites are collected over a 72-hour period and these specimens must be refrigerated or kept on ice during the collection process, including while the specimen is awaiting delivery to the lab. Essentially all other urine specimens are very time-sensitive, and allowing them to languish in the refrigerator instead of getting them to the lab can yield inaccurate results. The longer a specimen sits, the more chemical changes will naturally occur in the urine, and the less accurate a given test will be. This is why we usually ask you to peeatthe doctor's office instead of just sending you home with a plastic cup.
What information must be included on the specimen labels for the specimen to be accepted for analysis?
date of the patient
How can you regulate the pH of urine through diet?
The formation of renal stones is related to the urine pH. Patients being treated for renal calculi are frequently given diets or medications to change the pH of the urine so that kidney stones will not form. Calcium phosphate, calcium carbonate, and magnesium phosphate stones develop in alkaline urine; when this occurs, the urine is kept acidic. Uric acid, cystine, and calcium oxalate stones precipitate in acidic urine; in this situation, the urine should be kept alkaline or less acidic than normal. Drugs such as streptomycin, neomycin, and kanamycin are effective in treating urinary tract infections if the urine is alkaline. During treatment with sulfa drugs, alkaline urine helps prevent formation of sulfonamide crystals. Here are important points to remember about urinary pH: * An accurate measurement of urinary pH can be done only on a freshly voided specimen. If urine must be kept for any length of time before analysis, it should be refrigerated. * During sleep, decreased pulmonary ventilation causes respiratory acidosis. As a result, a first waking urine specimen is usually highly acidic. * Bacteria causing a urinary tract infection or bacterial contamination will produce alkaline urine. * A diet rich in citrus fruits, most vegetables, and legumes will keep the urine alkaline. * A diet high in meat and cranberry juice will keep the urine acidic. * Urine pH is an important screening test for the diagnosis of renal disease, respiratory disease, and certain metabolic disorders. * If urine pH is to be useful, it is necessary to use pH information in comparison with other diagnostic information. * All this text is taken from the site below: * http://www.rnceus.com/ua/uaph.html
Why is the specimen prepared for a monocular microscope must be very thin?
because the specimen is always thin
Why must you always use the low power lens when you are first focusing on a specimen?
It is supposed to help you center on the specimen.
In mastectomy procedurethe specimen has been harvested for estrogen and progesterone receptor studies in what solution you must put the specimen?
Formalin
Why must the prepared specimen for a monocular microscope be very thin?
The specimen prepared for a monocular microscope must be very thin so light can pass through it easily. The light then goes through a series of lenses that magnifies the specimen to appear bigger
