43.3.4.3 Hemoglobin Type
If the hemoglobin type has been done as a part of newborn screening and results are documented on the chart, the test does not need to be repeated. It also may be performed at the provider's discretion, as appropriate for age and population groups. For instance, certain clients need this procedure to screen for sickle cell disease or trait, if not done previously.
The DSHS laboratory uses isoelectric focusing electrophoresis for hemoglobin type screening.
The laboratory reports the types of hemoglobin detected. Providers should compare reported test results to the expected ranges, which are noted on the patient report, to determine whether further testing, such as confirmation, is needed. If a hemoglobin variant is reported as "Other," a specimen can be submitted to a reference laboratory for further testing and confirmation.
