The sickling test operates on the principle of hemoglobin S (HbS) polymerization upon deoxygenation. By contrast, the solubility test involves the reduction of HbS using sodium hydrosulfite, followed by precipitation of lysed red blood cells. Hemoglobin (Hb) electrophoresis identifies Hb variants based...

ordered as part of prenatal testing, especially if one or both parents have family members with a hemoglobin abnormality. It may be ordered as a follow-up to abnormal results on aComplete Blood Count (CBC). It may also be ordered when someone has had a positiveHemoglobin Solubility test. ...
Because HbC-Harlem and Hb-Bart’s behave like HbS in the solubility test, they may give false positive results in tests for HbS. HbF is identified and quantitated by its resistance to denaturation by strong alkali. The hemolsyate is mixed with an alkaline buffer (pH 12.8) and incubated ...
All forms of SCD, as well as sickle trait, result in a positive sickle solubility test; therefore this procedure will not discriminate among these disorders. The Hb S mutation can also be detected by molecular methods. Differential Diagnosis The differential diagnosis of SCD includes other forms...
objectives: to evaluate the efficacy of the solubility test as a screening method for hemoglobin s detection in newborns compared to alkaline and acid hemoglobin electrophoresis . methods: a total of 1.988 cord blood samples from newborns at instituto materno infantil de pernambuco (imip) during the...
Abnormal results need full evaluation before a diagnosis is confirmed.Confirmatory TestingNewborn screening tests are not diagnostic and MUST be confirmed on a liquid blood specimen.Solubility testing (Sickle-dex) is not an appropriate test to use on infants.Different newborn screening findings in ...
