3. The obtained specific gravity value of the sample is corrected using correction coefficients a and
b .
SGx = a × SGx´ + b
SGx: Sample’s specific gravity after calibration correction
SGx´:
Sample’s specific gravity before calibration correction
SG
H
: Specific gravity reference of standard solution (high)
SG
L
: Specific gravity reference of standard solution (low)
K
H
: Specific gravity of standard solution (high)
K
L
:
Specific gravity of standard solution (low)
Furthermore, high concentrations of glucose (GLU) and protein (PRO) will affect specific gravity.
Therefore, specific gravity is corrected using the concentrations of glucose and protein obtained
from test strip measurement.
SG = SGx – C
