Clinical Scorecard: cfDNA’s Big Moment Has Arrived

At a Glance

Key Highlights

• cfDNA testing is gaining traction across multiple areas of pathology.
• It offers a complementary tool to traditional tissue biopsy for disease monitoring.
• Established applications include prenatal testing, oncology, and solid organ transplantation.
• Technical challenges include low cfDNA concentrations and the need for sensitive assay technologies.
• Integration into existing workflows requires strong preanalytic controls and robust bioinformatics.

Guideline-Based Recommendations

Diagnosis

• cfDNA should be integrated with clinical context and other laboratory data for accurate interpretation.

Management

• Use cfDNA testing to answer specific clinical questions that influence patient management.

Monitoring & Follow-up

• cfDNA supports longitudinal monitoring of disease burden, particularly in oncology and transplantation.

Risks

• Overutilization may occur without clear clinical indications; underutilization exists in transplant surveillance and transfusion medicine.

Patient & Prescribing Data

Patients undergoing prenatal testing, cancer patients, organ transplant recipients.

cfDNA testing can reduce the need for invasive procedures and provide insights into ongoing biological responses.

Clinical Best Practices

• Standardize specimen collection and processing for cfDNA assays.
• Implement robust bioinformatics pipelines for interpretation.
• Educate clinicians and laboratory staff on appropriate test utilization and interpretation.
