How long can a urine sample sit before it is sent to lab for testing without going bad?

How long can a urine sample sit before it is sent to lab for testing without going bad?

Depends : Some things such as glucose must be tested pretty quick as they are consumed by cells and bacteria in the urine. Cells deteriorate quickly, bacteria multiply quickly. Protein could deteriorate. The ph can change depending upon bacterial action. Sodium, potassium, chloride, an similar elemental analytes are unchanged in spite of temperature and or biologic processes. In general test asap. ...Read more

Is any brand of urine dipstick better than another at detecting uti?

Is any brand of urine dipstick better than another at detecting uti?

Brands differ: The strips test for nitrite produced by some utis. Certain strips also test for white blood cells . Some dipsticks can test for both, but most test for only one or the other. An area on the end of the strip changes color if you have uti, altho false positive and negative tests occur. Most urinary tract infections can be cured with antibiotics, but see your doctor. ...Read more

I had dipstick urine test everything else was negative expect blood shows +/- intact. What does it mean?

Repeat: I'm going to assume this is not just contamination from your monthly cycle. This will probably be repeated and maybe worked up if positive. Several percent of folks have hematuria for no reason that anyone can determine -- often it's from a particular gene, and it doesn't result in problems. ...Read more

Urine dipstick test showed PH 6. All other negative. Is 6 good or bad? Am I dying of kidney problems? Pls help. I checked it at home

Urine pH 6 is normal: PH 6 is very mildly acid & almost certainly good. Phs of between 5 & * are normal. PH 5 is more acid & is most common pH. PH 7 is neutral, i.e. neither acidic nor alkaline & same pH as water. PH 8 is slightly alkaline, & in most cases normal. Thus U R not dying of kidney problems. Hope this puts a smile on your face! ...Read more

Cloudy urine for 1week, tested at docs (dipstick analysis), he said my urine was fine albeit cloudy, the test was negative/normal, why is cloudy?

Cloudy urine for 1week, tested at docs (dipstick analysis), he said my urine was fine albeit cloudy, the test was negative/normal, why is cloudy?

Entirely normal: Same questioner as 2 days ago (?). Same reply: Cloudy urine is not abnormal if it occurs without other symptoms like painful urination, urgency, or discharge. It's due to intake of fluids, various foods, etc. Cloudiness usually is from microscopic phosphate crystals; you can check this possibility by adding a few drops of vinegar to a urine sample, which probably will turn it crystal clear. ...Read more

Hi I have just dipsticked my urine it show ph of 9 and leukocyte is this anything to worry about.

Stone?: Some bacteria like Proteus associated with Struvite stones produce an enzyme called Urease which increases urine pH and can produce white cells or leukocytes in the urine. This is one possibility. The second is that you are taking a medication that alkalinizes urine. Please review your med list. ...Read more

Why do I still have nitrates and leukocytes on my urine dipstick when the urine culture is negative?

Why do I still have nitrates and leukocytes on my urine dipstick when the urine culture is negative?

Many reasons: There are many possible reasons why a urine culture is negative but the nitrates and leukocytes are positive. 1. If your taking antibiotics then that would prevent growth of the urine culture. 2. The leukocytes and nitrates do not represent an actual bacterial infection but other viral, chemical, or environmental reasons for a positive result 3. Dipstick test or urine culture tests are false. ...Read more

Do normal ''standard'' urine dipstick tests measure protein/creatinine ratio? Or do they only calculate protein by mg/dl? Please answer

Do normal ''standard'' urine dipstick tests measure protein/creatinine ratio? Or do they only calculate protein by mg/dl? Please answer

ONLY PROTEIN : Standard urine dipstick only measures protein by colorimetric method. If urine is postive for protein, exclude false positive, eg fever, uti, exercise postural. If positive, quantify it by measuring both protein and creatinine in the urine. . 1+ corresponds to about 200-500 mg/24 hours, a 2+ to 0.5-1.5 gm/24 hours, a 3+ to 2-5 gm/24 hours, and a 4+ represents 7 gm/24 hours or greater. ...Read more

Urine dipstick showed nitrites, put on ab's. 3 days later, called and told no growth in culture, stop ab's. How can I have nitrites but no uti?

Urine dipstick showed nitrites, put on ab's.  3 days later, called and told no growth in culture, stop ab's.  How can I have nitrites but no uti?

Nitrites: While the presence of nitrites in urine usually signifies the presence of a urinary tract infection, it is possible that someone misread the strip. Another possibility is that the urine specimen stood too long and some bacterial contamination took place but the number of organisms was too small to make the culture results postive. The culture is the significant result. ...Read more

Sorry: I don't know what you are asking. Presence or absence of occult blood on dipstick does not prove or disprove stone. I can give you a meaningful answer if you can find out the size and location of your husband's stone.Look forward to finding your question again. ...Read more
