Results. Nine(45%) of the 20
stroke patients had clinical signs of dehydration and had a significantly higher admission median urea:creatinine ratio (P=0.02, Mann-Whitney U-test).There were no obvious relationships between urine specific gravity and urine colour
with the urea:creatinine ratio.
Of the 174 urine samples collected, the refractometer agreed with 70/174 (40%) urine test strip urine specific gravity and 117/174 (67%) urine colour measurements.
