reira,
No leh .. the strip was given to me b4 seeing Dr wong. If got high sugar level, then the nurse will let Dr wong know, and she will then advise me wat to do.
Like my last preg, i kena 2 or 3 times the strips turned colour. Then Dr wong told me to take the sugar drink in the morning, and test again. Wa lao eh ... the strip turned brown lor. But by that time, we didn't really zoom in on this problem, cos we got another bigger problem, which is the rupture of my waterbag.
