If called after hours about a low blood glucose value, inquire about:
*2 patient identifiers (for example name and date of birth).
*Any symptoms of hypoglycemia if known.
*Time of collection and time of collection by the lab. If delayed more than 4 hours, it is generally a false low blood glucose if there is no report of hypoglycemia signs, and the lab can generally be told to hold the release of the result, and the absence of centrifugation at the time of collection can be confirmed with the blood drawing site the following day. For each hour before centrifugation, plasma glucose decreases by approximately 0.3 mmol/L, 6 mg/dL or 7% per hour, and serum glucose by approximately 0.25 mmol/L, 4.5 mg/dL or 5% per hour.<ref>{{cite web|url=https://acutecaretesting.org/en/journal-scans/preanalytic-error-in-plasma-serum-glucose-measurement-examined|title=Preanalytic error in plasma/serum glucose measurement examined|author=Chris Higgins}} July 2019.
