Methodology

Spectrophotometry

Reported

STAT 1 hour, Routine 4 hours

Additional Information

Reference ranges are altered by the intensity of chronic exposure to high altitudes or tobacco smoke, or by the duration of pregnancy.

A manual hemoglobin assay will be performed whenever accurate results cannot be obtained on an automated instrument because of some intrinsic abnormality of the specimen.

Values are calculated from conductance hematocrit on iStat analyzer. Conductance methods for hematocrit may yield spurious results in patients with high volume crystalloid infusion (particularly patients on bypass pump) or other plasma protein derangements. Therefore hemoglobin values based on conductance may not compare well with measured Hgb results.
