#5014 Tried and Tested
See question above: What is indeed the correct way for blood sugar or alcohol testing on Shabbos?
Can someone that after a meal during Shabbos and needs to test blood sugar or alcohol levels insert clinical test strips into ones urine and check it by the changing of color on Shabbath?
As mentioned in more recent Teshuvos, for chronically diabetes patients continuous Glucose Monitors are available. See questions 2010 and 2086 for their use during Shabbos. In our days constant body attached monitors are common.
However, for one that does not use them, when in need indeed as mentioned it is permitted to use strips. Same applies to alcohol testing.
