Sorry, I've been kinda busy and haven't come to this forum for a while!

Zach90, I also asked Guardian about Ketostix last year, and they sell a more expensive type (if I recall, around SGD16 a box?) that not only tests for ketones but other stuff in the urine as well. The pharmacist said they stopped carrying the pure ketostix due to low demand! I eventually got my ketostix from my sis in US...

For the record, I'm definitely way beyond my teens
