Urinary pH ( acid or alkaline ) reflects the ability of the kidney to maintain a normal concentration hihrogen ions ( H + ) in plasma and extracellular fluids . The normal concentration of H ions in the range of pH = 4.6 to 8.0 , but in most cases the pH is around 6.0.
The simplest procedure to determine the pH of urine is the specific bands with the help of which, in contact with the patient’s urine sample changes color. An alkaline urine pH ( > 7 ) is the result of a diet rich in vegetable protein , dairy and citrus , can cause the formation of crystals of phosphate , carbon . Also, alkaline urine may be due to a urinary tract infection or metabolic or respiratory alkalosis .
An acid urine pH (<7 ) may be due to a diet rich in protein can lead to the formation of oxalate , urate . Also, acidic urine can be caused renal tuberculosis , diarrhea and other forms of acidosis .
- container harvesting specific
- bands urinary pH measurement
- standard card reader
confirmation and verification of patient identity
Wash hands and put gloves
patient and explains procedure
patient is given vessel and shall explain how to collect a urine sample (see ” Sampling of urine ” )
band dives according to the prospectus , and read user .
Special considerations :
will use a urine sample collected at the time of the test , not long before , as lying at room temperature the sample changes its pH .
will take into account that usually at night urine pH is more acidic than diurnal urinary pH .
