Lit-Control ® pH Buffer

In order to keep this solution in proper condition for as long as possible, it is advisable to follow these precautions:

1. Note the date of first use; after one month replace the calibration solution with a new one.

2. Keep the beaker with calibration solution screwed to the device during storage.

3. Store the calibration solution between 5°C and 45°C.

4. Avoid direct exposure of the calibration solution to sunlight.

1. Unscrew the beaker and pour in the calibration solution.

2. Screw the cup back onto the device.

3. Gently shake the device for 5 seconds.

4. Press the button until the device turns on and wait for the ‘C’ symbol to appear on the display. display.

5. Press the button once for calibration to begin.

For the duration of the calibration, a moving dot will be displayed below the symbol. Wait for a few seconds, if the calibration is successful, the ‘T’ symbol will be shown on the display.

Urinary pH is an indicator of the acidity or alkalinity of urine and provides information about the overall health of the body. general state of health of our body. The average pH value is around 6.2. However, due to its However, due to its oscillating behaviour it can range from 4.5 to 8, depending to a large extent on the diet, waste products, metabolic disturbances, and other causes.

There are currently two options for urinary pH monitoring: by test strip or by laboratory pH meter. laboratory pH-meter. The former are widely questioned by the medical community for their low accuracy and fiability for clinical decision making; while the latter lacks the portability of a pH meter. fiability for clinical decision making; while the latter lacks the portability necessary for urinary pH necessary for the measurement of urinary pH to be made in freshly voided urine, which has fisiological value. fisiological value.

• If crystals are present in the urine and the urinary pH is above 6.2, conditions are suitable for the formation of infectious or calcium phosphate, or calcium phosphate-induced calcium oxalate stones. If crystals are present in the urine and the urinary pH is above 6.2, conditions are suitable for the formation of infectious or calcium phosphate, or calcium oxalate-induced calcium phosphate stones.

• If crystals are present in the urine and the urinary pH is below 5.5, conditions are suitable for the formation of cystine or uric acid, or uric acid-induced calcium oxalate stones. If crystals are present in the urine and the urinary pH is below 5.5, conditions are suitable for the formation of cystine or uric acid, or uric acid-induced calcium oxalate stones.

• On certain occasions, or without pH alteration, the simple existence of crystals and the lack of fisiological inhibitors of this crystallisation, can favour the formation of kidney stones. In certain cases, or without pH alteration, the simple existence of crystals and the lack of fisiological inhibitors of this crystallisation, can favour the formation of kidney stones.

Correct control of urinary pH will reduce the risk of kidney stone formation.

After placement of a bladder catheter or double j catheter, a urinary tract infection tends to develop, which in most cases can lead to alkaline urine. If the infection persists due to, among other things, the presence of crystals in the urine and an alkaline pH, it may lead to calcification of the catheter or catheter, even obstructing it and in some cases making it difficult to remove.
