Which organization is listed as a source for health screening information?

• A. Mayo Clinic
• B. NIH
• C. labtestonline.org
• D. nbsalliance.org

Answer: (B)

Credible, evidence-based health screening information typically comes from major health organizations that fund and review scientific research. The National Institutes of Health is such an organization; as a U.S. government agency, it provides reliable, up-to-date consumer health information and screening guidelines through resources like MedlinePlus and NIH-supported research. This makes it a trusted source for understanding which screenings are recommended, what the results mean, and how to interpret findings in a general health context. Other options may offer valuable information—Mayo Clinic provides patient-focused medical guidance, labtestonline.org explains lab tests, and nbsalliance.org focuses on newborn screening—but the NIH is the most widely recognized official source for broad health screening information.
