How We Research and Source Our Content
LabAppointments.com publishes educational guides about laboratory testing. Every guide is written to answer a specific question a reader may have about a test, and is reviewed for sourcing accuracy before it is published.
We source medical and scientific information only from reputable public health and clinical organizations, including the U.S. Centers for Disease Control and Prevention (CDC), the National Institutes of Health (NIH), the National Library of Medicine (MedlinePlus), and the U.S. Food and Drug Administration (FDA). Each guide lists the specific sources used.
We do not provide medical advice, diagnosis, or treatment, and we do not give dosing or medication guidance. Reference ranges and clinical guidance vary between laboratories and change over time, so readers should always confirm their own results and care with a qualified healthcare provider.
Guides are reviewed periodically and updated when guidance or testing options change. If you spot an error or an outdated source, please contact us and we will review it.
We may earn commissions from affiliate links to testing partners. This does not influence the educational content we publish, and it does not change the price a reader pays.
