The table at the bottom of the page depicts the drastic differences in wear between Ester and end-capped PAG. 100% Compatibility with R12 or R134a and Residual Mineral Oil Double end-capped PAG is compatible with both R12 and R134a and can be used in either application (even with residual oil).AG oil is not compatible with R12 and must not be used in older R12 systems. Mineral-based compressor oil should only be used in older vehicles with R12. Mineral oil must never be used with R134a because the two will not mix.
1 Oral glucose tolerance test. 2  For this test, you fast overnight, and the fasting blood sugar level is measured. 3  Then you drink a sugary liquid, and blood sugar levels are tested periodically for the next two hours. 4  A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal.
Fasting blood glucose: A test to determine how much glucose (sugar) is in a blood sample after an overnight fast. The fasting blood glucose test is commonly used to detect diabetes mellitus. A blood sample is taken in a lab, physician's office, or hospital. The test is done in the morning, before the person has eaten. The normal range for blood glucose is 70 to 100 mg/dl. Levels between 100 and 126 mg/dl are referred to as impaired fasting glucose or pre-diabetes. Diabetes is typically diagnosed when fasting blood glucose levels are 126 mg/dl or higher.
