Home test for urinary tract infections
Nitrite dipstick test:No nitrite is found in the urine. Normal results are called negative.
Leukocyte dipstick test:No white blood cells (leukocytes) are found in the urine. Normal results are called negative.
Nitrite dipstick test:Nitrite is found in the urine. These results are called positive.
Leukocyte dipstick test:White blood cells (leukocytes) are found in the urine. These results are called positive.
Negative nitrites and leukocytes indicate presence of no bacteria. Negative nitrite and low leukocytes indicate positive test for infection. pH of 7 is normal.

Do negative nitrites and Leukocytes always indicate low bacteria levels typically? DO they ALWAYS indicate bacteria that harm the body or are there always times during the day that some bacteria finds its way into the bladder and the body gets rid of it somehow?
What does S.G. Densite mean?
Negative nitrites and leukocytes indicate no bacteria. They always indicate harmful bacteria and not harmless bacteria. SG is specific gravity of urine. This test helps evaluate your body’s water balance and urine concentration. Normal values are between 1.020 to 1.028.
When the nitrite dip shows up as trace and not positive and leukocytes are at +25 and not ++75 nor +++500...., What does this mean?
And does urine frequently have nitrite and leukocytes? Also, if the SG goes to 1.015 or 1.030, what does this indicate and can it move back into normal range quickly?
Also, can there be a very established large colony of bad bacteria but the urine test strip often comes out with negative nitrites and negative leukocytes and are there other markers or parameters to test the urine for which could also point to a heavy population of bad bacteria or ailment indicated by urine samples? The urine strips I have test 11 items.
Trace nitrite and low level of leukocytes indicate a low level of infection. Urine does not frequently have nitrite and leukocytes, it is present only in the case of infection.
Increased specific gravity of urine may be due to the following reasons:
Increased urine specific gravity may be due to:
It can move back into normal range quickly depending upon the cause that has caused this increase such as if dehydration has caused the increase in specific gravity, it can return to normal when you drink lots of fluids and dehydration is corrected. No there can not be a very established large colony of bad bacteria but the urine test strip comes out negative nitrites and negative leukocytes. The other test items apart from nitrites and leukocytes may indicate other ailments apart from presence of bacteria.
Also, unless the person wipes and cleans themselves first with alcohol wipes before peeing, the results gotten from the urine stream are typically useless? Or will some markers on the strips still be able to reveal or hint at health issues?
These are the strips I am using at the moment to try and motivate my father to shower more and my mother to drink more liquids.
Yes, peeing and testing without wiping and cleaning will make the test results useless as it may lead to contamination of the urine sample. No it is best to wipe and clean and then pee for the test, there is no use of the test done in urine sample taken without wiping and cleaning. The test strips you are using are fine.
