Use: The hemoglobin test is useful for identifying individuals with conditions affecting red blood cells, or individuals with symptoms including weakness, fatigue or shortness of breath. It can also be used to monitor the efficacy of treatment for anemia.
Limitations: An extremely elevated white blood cell count may cause an increased hemoglobin value. Abnormal paraproteins found in multiple myeloma patients, lipemia or severely icteric samples can falsely increase hemoglobin results. Hemoglobin S, C and F, or hereditary or acquired spherocytosis may cause an increase in hemoglobin values. Removal of plasma from a sample will cause falsely elevated hemoglobin results.
Additional Information: Hemoglobin levels can be affected by recent transfusions, and are slightly lower during pregnancy.
