Ok Keto experts, just got back from the doctor and he noticed something. My blood ketone levels are about 16 times the normal range, which is to be expected after 3 months of keto and lots of MCT oil. However, my urine was negative for ketones! Does that make sense? I don’t have any urine strips to test it, but seems to me a lab should at least detect something. Any reason blood levels could be so high and urine still negative?
