Evidence Hierarchy

How We Rank Medical Research Evidence

Every clinical service and reference guide in our health library is graded based on the Oxford Centre for Evidence-Based Medicine (CEBM) criteria. Systematic reviews of randomized controlled trials (Level 1) form the foundation of our clinical recommendations, followed by individual blinded RCTs (Level 2). In vitro and animal studies are never cited to support human clinical efficacy claims.

Frequently Asked Questions About Our Clinical Services

Straight answers on insurance coverage, laboratory logistics, physician credentials, and medical privacy.

Are HealthVitalnuvia clinical services covered by insurance, HSA, or FSA?

Yes. All diagnostic laboratory orders, ambulatory telemetry kits, and physician telehealth consultations are eligible for HSA (Health Savings Account) and FSA (Flexible Spending Account) reimbursement. We provide comprehensive, itemized superbills with standard CPT and ICD-10 diagnostic codes suitable for direct insurance submission.

How and where are laboratory specimens collected?

Blood draws and serum assays are performed at nationwide CLIA-certified and CAP-accredited partner patient centers (including Quest Diagnostics and Labcorp). When ordering at-home services (such as Type 3 sleep apnea sensors or continuous glucose monitors), testing kits arrive directly at your residence with prepaid return packaging.

Who conducts the telehealth consultations and reviews my results?

Every consultation is conducted by actively practicing, board-certified medical doctors (MD/DO) or registered pharmacotherapy specialists licensed in the United States. We never employ artificial intelligence bot diagnostics or unqualified wellness coaches to interpret clinical biomarker labs.

Can I share my clinical reports with my Primary Care Physician (PCP)?

Absolutely. Our clinical care summaries are formatted specifically for physician-to-physician transmission, containing exact reference ranges, laboratory methodology, and clinical recommendations so your primary care provider can integrate the findings seamlessly into your electronic health record (EHR).
