Hi Ling Ling, if blood test do on 1st day, result is not accurate and waste ur time and money. must be either on 2nd or 3rd day (if 2nd day is on Sunday then go on Monday - 3rd day). you can try calling KK IVF hotline or clinic D number. hopes this help.
some spree organiser just show a general shipping invoice which did not indicate anything but the amount paid to vpost.
if u r honest as a spree organiser, show to the spreeist the shipping invoice which is directly related to that particular spree.
