Clinical Scorecard: Rethinking Wearables: Why Scientists Are Turning to Sweat

At a Glance

Key Highlights

• Sweat collection is noninvasive and has fewer contaminants than blood or urine.
• Pilocarpine iontophoresis is the standard method for cystic fibrosis diagnosis.
• Wearable sensors can measure glucose and β-hydroxybutyrate for diabetes monitoring.
• Proteomic analysis of sweat shows potential for diagnosing tuberculosis and autoimmune conditions.
• Advances in technology are moving sweat testing towards continuous monitoring.

Guideline-Based Recommendations

Diagnosis

• Use pilocarpine iontophoresis for cystic fibrosis diagnosis with chloride levels above 60 mmol/L.

Management

• Consider sweat testing for noninvasive monitoring of diabetes and other metabolic conditions.

Monitoring & Follow-up

• Utilize wearable sensors for continuous monitoring of glucose and other biomarkers.

Risks

• Analytical challenges include low analyte concentrations and potential contamination.

Patient & Prescribing Data

Patients with metabolic, infectious, and inflammatory diseases.

Emerging use of sweat analysis for noninvasive diagnostics and monitoring.

Clinical Best Practices

• Ensure proper sampling controls to correlate sweat glucose with blood glucose.
• Investigate normalization techniques for sweat volume to improve analyte quantification.
• Stay updated on technological advances in microfluidics and wearable electronics.
