Limitation

This collation does not set “normal” ranges for the values. Valid ranges account only for data collection extremes. There is a conversion for this collation for sites that use alternate units.

Data quality is limited to individual site documentation accuracy, completeness, and variable mapping, which is performed by each site, independently. MPOG, as the coordinating center, reviews data quality at each data upload and monthly via Data Diagnostics and Case Validation tools. This review, while thorough, may not contain all data elements relevant to this phenotype and thus should be carefully reviewed by the user.

Values collected under MPOG ID 5057 (Formal Lab – Albumin Serum/Plasma)

All values converted to g/dl.

Obtain most recent (latest) valid serum albumin level in g/dL prior to anesthesia start and within 365 days of anesthesia start with number of days prior to surgery

Valid: >0 g/dL and <50 g/dL
If data invalid ? Output = -998
If data valid ? Output = (numeric value in g/dL)

General reference ranges

3.5-5.5 g/dl (Conventional Unit) ^1,2,3
35-55 g/l (SI Unit) ²
Mild hypoalbuminemia 2.5-3.5 g/dl ⁴
Severe hypoalbuminemia: < 2.5 g/dl ^{4, 5}
Low: case report: 1.1 g/dl4
Limited data on hyperalbuminemia. Case report 5.7 g/dl ⁵

Conversion to g/dl before classifying as valid or invalid
