Sickle SCAN POC test. The Sickle SCAN results are noted by the presence of a band aligned with each hemoglobin type, including HbA, HbC, and HbS, with a control band to ensure the test is working properly. The Sickle SCAN test can qualitatively identify the presence or absence of HbA, HbS, and HbC and can accurately distinguish the most common forms of SCD (HbSS and HbSC) from the carrier states (HbAC and HbAS).
