Hemoglobin-SC-Algorithm - Clinical Screening Protocol

Sep 29, 2026

Uploaded by iuabcfuw

This document outlines the clinical algorithmic workflow for evaluating Hemoglobin SC (HbS/C) screening results within a newborn screening context. It provides a structured diagnostic pathway, starting from the initial FSC (Hemoglobin Sickle Cell) findings, proceeding through confirmatory tests such as CBC, capillary zone electrophoresis, IEF, or HPLC, and concluding with genetic counseling recommendations. The resource serves as a professional guideline for medical geneticists and clinicians to facilitate consistent, high-quality diagnostic processes for hemoglobinopathies. It emphasizes the necessity of professional judgment in interpreting results, differentiating between confirmed hemoglobinopathies and false-positive cases. The inclusion of molecular genetic testing options highlights the advanced diagnostic approach for definitive identification of hemoglobin traits, supporting comprehensive patient care and genetic education in accordance with standards set by the American College of Medical Genetics and Genomics.

FAQs

What initial steps should be taken following an abnormal FSC screening result?

The protocol recommends consulting with a sickle cell expert and performing follow-up tests including a complete blood count (CBC), red blood cell smear, and advanced hemoglobin analysis via capillary zone electrophoresis, IEF, or HPLC.

What is the clinical significance of a HbA result in this algorithm?

If the secondary testing results indicate HbA and are not consistent with a hemoglobinopathy, the initial newborn screening result is considered a false positive, and this should be reported to the appropriate screening program.

When is molecular genetic testing indicated?

Molecular genetic testing is identified as an optional, secondary step indicated following the confirmation of HbS/C results to provide further diagnostic clarity prior to referring the patient for genetic counseling.
