The correction of urine specific gravity for temperature is to add 0.001 to specific gravity reading for each 3 degree Centigrade above calibration temperature. Alternatively, subtract 0.001 for each 3 degrees below calibration temperature.


Measurement of specific gravity: refractometer


correction factor for temperature =

= (((temperature in centigrade) - (calibration temperature)) / 3) * 0.001


urine specific gravity corrected for temperature =

= (measured specific gravity) + (correction factor for temperature)
