Overview
Diagnostic criteria of hypoglycemia include symptoms of hypoglycemia, a low plasma glucose concentration correlated with symptoms, and correction of glucose level relieves symptoms. These criteria called Whipple's triad. Neonatal hypoglycemia can be diagnosed by measuring multiple metabolic panels include plasma insulin, plasma C-peptide, beta-hydroxybutyrate, blood pH, bicarbonate, lactate, Free fatty acids, acylcarnitine profile, plasma free and total carnitine levels.
Hypoglycemia diagnostic criteria
The following 3 characteristics should be present to diagnose hypoglycemia, which is called Whipple's triad and includes:[1][2]
- Symptoms of hypoglycemia
- A low plasma glucose concentration correlated with symptoms
- Correction of glucose level relieves symptoms
The strategy is to seek Whipple's triad under conditions in which hypoglycemia would be expected:[3][4]
- If the symptoms occur in the fasting state, that evaluation should be performed during fasting.
- If there is a compelling history of postprandial symptoms, it is reasonable to seek Whipple's triad with frequent, timed plasma glucose measurements and recording of any symptoms after a mixed meal.
Identifying the cause
After confirmation of hypoglycemia. Physicians should have history, signs and laboratory results sufficient to help them to identify the cause of hypoglycemia:[5]
| Plasma insulin[6] | C-peptide | proinsulin | Sulfonylurea in plasma | insulin or insulin receptor antibodies | Postprandial symptoms | Fating symptoms | |
|---|---|---|---|---|---|---|---|
| Insulinoma | high | high | high | - | - | - | + |
| Oral hypoglycemics | high | high | high | + | - | - | - |
| Autoimmune hypoglycemia | high | high | high | - | + | - | - |
| NIPHS* | high | high | high | - | - | + | - |
| Exogenous insulin | high | low | low | - | - | - | - |
| Non-islet cell tumors | low | low | low | - | - | - | - |
*(NIPHS) non-insulinoma pancreatogenous hypoglycemia syndrome
Neonatal hypoglycemia:
- Measure plasma insulin, plasma C-peptide and beta-hydroxybutyrate
- Blood pH, bicarbonate, and lactate
- Free fatty acids, acylcarnitine profile, plasma free and total carnitine levels
