If your patient has a history consistent with an IgE-mediated reaction to penicillin, then consider a penicillin skin test. Skin tests can be done when the patient is well and does not need an antibiotic. Then, if the patient becomes ill at a later time, a penicillin antibiotic can be used, if indicated.
A normal blood sugar level is between 72 mg/dL and 108 mg/dL (4 to 6 mmol/L) for a healthy person. The concentration of glucose in the blood of a healthy person in the morning on an empty stomach is between 68 mg/dL and 108 mg/dL (3.8 and 6.0 mmol/L).
Quick Answer. Acceptable blood glucose levels are 100 milligrams of glucose per deciliter after a fasting blood glucose test; less than 140 mg/dL for people 50 years old or younger; less than 150 mg/dL for people 50 to 60; and less than 160 mg/dL for people over 60, states WebMD. Random glucose levels depend on when the patient had his last meal.
