GLOSSARY

Oral Glucose Tolerance Test (OGTT)
An oral glucose tolerance test measures glucose handling after a standardized glucose load under specified preparation conditions.

Separate biological and analytical effects

Hormone results depend on secretion rhythms, binding, clearance, sample handling and the measurement method. Reference intervals and decision thresholds serve different purposes. Assay-specific interpretation is especially important near low concentrations and when results conflict with the clinical picture.

Interpreting the mechanism

• Diagnostic interpretation depends on the clinical setting, including pregnancy, and the procedure is distinct from simply measuring glucose after an ordinary meal.

Define the testing question

Dynamic tests examine a regulated response under specified conditions. Their protocols, contraindications and thresholds require clinical oversight. A glossary explanation supports understanding and does not provide a self-testing or medication-adjustment protocol.
