Yes, Quest is typically open on Sunday, including most holiday Sundays, though operating hours may vary by location and specific holiday. If you're asking 'is Quest open on Sunday' for a particular date—especially around major holidays like Easter, Memorial Day, or Labor Day—the answer generally remains yes, but with potential adjustments. As a service-focused brand often integrated into health, wellness, or diagnostic networks, Quest locations such as patient service centers (PSCs) usually maintain Sunday availability to accommodate patients who prefer weekend appointments. However, not all Quest facilities follow the same schedule. Factors including regional regulations, staffing models, and facility type influence whether a given center operates on a holiday Sunday. For accurate planning, always verify your local center’s hours using the official Quest website or customer service line.
Quick Overview: Is Quest Open on Sundays?
In general, many Quest Diagnostics patient service centers are open on Sundays, particularly in urban and suburban areas where demand for weekend blood work and lab testing remains high. Standard Sunday hours typically run from 8:00 AM to 12:00 PM, though this varies significantly by location. Unlike retail chains that close on major holidays, Quest maintains limited operations even on certain holidays that fall on a Sunday—such as Easter or Mother's Day—but full closures occur on core national holidays like Thanksgiving, Christmas Day, and New Year’s Day, regardless of the weekday.
It's important to note that while Sunday access is common, it is not guaranteed across all 2,000+ Quest locations nationwide. Some centers located within hospitals or clinics may follow partner institution schedules, while standalone PSCs often have more flexible weekend access. The key takeaway: most Quest centers are open on non-holiday Sundays, but holiday observances can alter this pattern.
Typical Holiday Operating Policy at Quest
Quest Diagnostics follows a standardized holiday closure policy for its patient service centers, which affects both weekday and weekend operations. The company generally closes on six major U.S. holidays each year:
- New Year’s Day
- Martin Luther King Jr. Day (some locations open)
- Memorial Day
- Independence Day (July 4th)
- Thanksgiving Day
- Christmas Day
If any of these holidays fall on a Sunday, the center will be closed on that day. In cases where a holiday is observed on a different date (e.g., when July 4th falls on a Saturday, and the federal observance shifts to Friday), Quest typically aligns with the actual calendar date rather than the observed one. This means if July 4th lands on a Sunday, Quest centers will be closed that Sunday.
The decision to close stems from reduced physician referrals, lower patient volume, and staffing considerations. However, emergency departments and hospital-based labs associated with Quest may still process urgent tests—even if outpatient centers are closed.
Why Store Hours Vary Across Locations
Not all Quest centers operate under identical schedules due to several structural and logistical factors:
- Facility Type: Standalone patient service centers are more likely to offer Sunday hours than those embedded in third-party medical offices or hospitals.
- Franchise vs. Corporate Ownership: While Quest Diagnostics is primarily a corporate-run network, some partnerships with healthcare providers mean scheduling autonomy exists in select regions.
- Local Regulations: State laws governing clinical laboratory operations, especially regarding specimen transport and technician availability, can affect weekend access.
- Urban vs. Rural Demand: High-population areas like Los Angeles, Chicago, and Atlanta see greater demand for weekend testing, prompting extended Sunday access compared to rural locations.
- Mall or Medical Plaza Location: Centers inside larger medical complexes may adjust hours based on building access or shared staffing resources.
Because of these variables, two Quest centers just miles apart might have completely different Sunday availability—especially during holiday weekends.

Holiday-Specific Factors Affecting Sunday Operations
When evaluating whether Quest is open on Sunday during a holiday period, consider the nature of the holiday itself. Not all Sundays are treated equally in the healthcare sector.
Easter Sunday
Easter is one of the few religious holidays that consistently falls on a Sunday. Unlike federally recognized holidays, Easter does not trigger automatic closures at Quest. Many centers remain open with modified hours, especially in regions with higher Christian populations. Patients needing fasting blood tests before Easter dinner often schedule early morning draws. However, availability is not universal—checking ahead is essential.
Mother’s Day
Mother’s Day, though widely celebrated, is not a federal holiday. Most Quest centers treat it as a regular Sunday, maintaining standard operating hours (typically 8:00 AM – 12:00 PM). It's a popular day for families to assist aging parents with health checkups, so walk-ins may experience slightly longer wait times.
Memorial Day & Labor Day
These federal holidays fall on the last Monday of May and first Monday of September, respectively. But if they were to fall on a Sunday (as per calendar rotation), Quest would be closed. These holidays are treated as full operational shutdowns for outpatient centers, reflecting reduced staffing and referral activity.
Christmas Day and New Year’s Day
If either holiday lands on a Sunday, all Quest patient service centers are closed. No routine testing is performed, though critical care specimens from hospitals continue to be processed through centralized labs. Rescheduling options are available online for affected appointments.
Weekend Proximity Effects
Holidays immediately before or after a Sunday also impact operations. For example:
- Saturday before Christmas: Extended hours possible; high patient volume expected.
- Day after Thanksgiving (Black Friday): Most centers open with normal Friday hours; no special weekend adjustments.
- New Year’s Eve (if on Saturday): Sunday, January 1st centers remain closed even if the new year began the prior evening.
This shows that adjacent days do not override official holiday closure rules.
Practical Planning Tips for Patients
To ensure you don’t arrive at a closed location, especially on a holiday Sunday, follow these actionable steps:
1. Check Online Before You Go
The most reliable method to confirm if Quest is open on Sunday is to use the official Quest Diagnostics website. Use the "Find a Location" tool to search your ZIP code or city. Each listing includes:
- Detailed Sunday hours
- Holiday-specific closures
- Appointment requirements
- Phone number for direct contact
2. Call Ahead for Immediate Confirmation
If you’re unsure about automated listings, call the local center directly. Staff can confirm whether the site is open on a given Sunday, especially near holidays. The national customer service line (1-800-QUEST-33) also provides holiday hour support.
3. Use the Quest Mobile App
The Quest app allows users to view nearby center hours, book appointments, and receive alerts about temporary closures or schedule changes—all in real time.
4. Plan Alternative Dates Early
If your preferred Sunday is closed due to a holiday, reschedule your lab work 1–2 days earlier. Avoid last-minute rushes on Saturdays preceding major holidays, as wait times increase.
5. Consider At-Home Test Kits
For non-urgent screenings (cholesterol, vitamin D, thyroid), Quest offers at-home collection kits. These eliminate the need to visit a center altogether and are ideal during holiday periods when access is limited.
