Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Hemoglobin transports oxygen and CO2. This activity is decreased in anemia and increased in polycythemia, erythrocytosis, and dehydration.
Hemoglobin measurements are used as clinical guides in the diagnosis or monitoring of many diseases.
Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Interpretation
Provides information to assist in interpretation of the test results
Results outside of normal value ranges may reflect a primary disorder of the cell-producing organs or an underlying disease. Results should be interpreted in conjunction with the patient's clinical picture and appropriate additional testing performed.
Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
Questionable results are detected by in-house checking criteria based on quantitative and qualitative parameters.

Method Description
Describes how the test is performed and provides a method-specific reference
The sodium lauryl sulphate-hemoglobin (SLS-HGB) detection method uses cyanide-free SLS. The reagent lyses red and white blood cells in the sample. The chemical reaction begins by altering the globin and then oxidizing the heme groups. Then the hydrophilic portions of the SLS bind to the heme group and form a stable, colored complex (SLS-HGB), which is analyzed using a photometric method.
An LED sends out monochromatic light and by moving through the mixture, light is absorbed by the SLS-HGB complexes. The absorbance is measured by a photo sensor and is proportional to the hemoglobin concentration of the sample. This method is usually less influenced by specimen turbidity caused by interferences such as lipemia and leukocytosis.(Instruction manual: Sysmex XN-9000, August 2012, Kobe, Japan; adapted from Sysmex Europe Knowledge Centre 2017)
PDF Report
Indicates whether the report includes an additional document with charts, images or other enriched information
Day(s) Performed
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.
Monday through Friday
Report Available
The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.
Specimen Retention Time
Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
Performing Laboratory Location
Indicates the location of the laboratory that performs the test
