I have hybrid dwarf hamsters, and both tested positive for diabetes- signs were drinking a lot if water, and the smell of their urine, smelled more like a chemical smell, than urine. I'd say, the first thing to do, is give your hamster time to adjust to a sugar free hamster mix, so that the results are as accurate, as possible, as any sugar eaten by your hamster may produce a higher reading. ( if your ham is diabetic) If your instincts are telling you their maybe health issues with your dwarf, test him- that will give you peace of mind , and allow you to have a vet check, if need be.
Diet is very important for an diabetes prone hamster. Molasses, honey, refined sugar, and natural sugars found in fruit should be avoided. I feed my dwarf hamster Hazel Hamster mix, which is sugar free. There are also " block" food, such as Harland Tekland 2018 that is an option for dwarfs.
As far as taming. Basing when it's the right time to start taming, based on the days you've had the hamster, is true in some cases, but like people, hamsters have individual needs, personalities, and past histories. With that said, I base the start of taming, based on how the hamster is behaving.
With the 2 dwarf hamsters, I've had and an Chinese hamster, their needs, personalities, and comfort levels on starting taming, all differed.
What I'd suggest to you, is when your hamster, starts to feel comfortable within your presence, becomes comfortable when your hand is in their cage, and taking food/a treat from your fingers, then that's a sign taming can proceed to the next step. My best advice taming a dwarf hamster, is allow the hamster to come to you, and he/she will, the more comfortable and familiar the hamster is with you.
This may take, weeks, even a month (s) but believe me, your patience and going at your hamsters pace, will pay off in the end
