You respond to the home of a 56 YOM for a 3rd party caller reporting their family member is confused. Upon arrival, you note that the patient has diabetic medications in the house as well as an IV pump with a medication you are not familiar with. Blood sugar on your glucometer is 148 mg/dl. You transport him to the hospital, where lab glucose determines that he is actually hypoglycemic.
The patient was taking a medication called Extraneal, which contains Icodextrin and is used for peritoneal dialysis. This can affect certain types of glucometers, leading to false high readings. Do you know which type of glucometer you have? Find out here.
Here are common types:
- Glucose Dehydrogenase Pyrroloquinoline Quinone (GDH-PQQ)
- Glucose Dehydrogenase Flavin-Adenine Dinucleotide (GDH-FAD)
- Glucose Dehydrogenase Nicotinamide-Adenine Dinucleotide (GDH-NAD)
