LabRequirements

LabRequirements is an independent U.S. directory designed to help people understand what to expect before getting a laboratory test. It explains practical requirements such as fasting and other preparation, photo identification, referrals, and typical turnaround times, helping visitors plan before they go to a collection site. Users can search or browse 665 laboratory tests, read plain-language summaries of what tests measure, and explore availability across 15,280 communities in all 50 states and territories.

The directory features tests covering a range of needs, including sexually transmitted infections, liver markers, and food and environmental allergies. It also publishes educational guides that explain how test groups work, what results may indicate, and the limitations of certain tests. Visitors can browse by state and follow links to order tests online. LabRequirements may earn commissions from qualifying orders made through outbound links, at no additional cost to the customer. The site is not a healthcare provider and does not offer medical advice; it recommends confirming preparation instructions, availability, hours, and pricing with the collection laboratory.
