In 1975 there was compelling evidence that glycaemic
control in pregnancy was critical for a successful outcome for mother and baby. However, diabetic control could be monitored only by the
women testing the urine for reducing substances. The renal threshold
for glucose not uncommonly falls in pregnancy with resultant glycosia
when the blood glucose values are still in the normal range. The
instruction to diabetic pregnant women was to keep "the urine blue"
(clinitest tablets were still in use and when five drops of urine and
10 drops of water were added to the clinic test tablet the mixture
would remain blue if free of reducing substances). My patient had
obeyed this instruction, but unfortunately for her, and perhaps
fortunately for the diabetic fraternity, she developed a drastic
reduction in her renal threshold for glucose, which resulted in a
prolonged hypoglycaemic episode. So at 26 weeks of pregnancy I advised
her to
