Comparison of urinary specific gravity by refractometer and osmolality in 238 neonates
demonstrated as followings;
1) The regression line is represented by the equation:
Y = 107+14.2 (X-1000)
while Y = osmolality in mosm/kg
X = Specific gravity by refractometer
r=0.8545
2) Osmolality is the only accurate measure of urine concentration in newborn infants. If the specific
gravity by refractometer is used to screen for urine concentration, an elevated level... |
