Best Online Doctors That Order Lab Tests in San Francisco (2026)
Quick Answer
San Francisco has Quest and Labcorp draw sites from Chinatown to the Mission; the question is who signs the order and what that costs. Momentary is the cheapest physician route: $19.99 a month gives San Francisco residents, like every Californian, a licensed California physician to message at any hour who picks the panels, sends the requisition to an SF Quest or Labcorp site, and explains the results; the lab bills its fee separately. To skip the doctor, questhealth.com and Labcorp OnDemand sell a CBC for $29 and a CMP for $49 with an independent physician's order built in. A MyChart message to your UCSF or Sutter PCP may cost $0 to about $20, and uninsured San Franciscans can get labs through a Healthy San Francisco medical home for $0 to $20.
Momentary is our own product. Where a $29 self-ordered test or a message to a doctor you already have costs less, we say so.

Why People Search for Online Doctors That Order Lab Tests in San Francisco
In San Francisco the request usually arrives fully formed: a fasting lipid panel before a statin, a TSH after months of dragging, an A1c because a parent was just diagnosed. Three local facts decide where to get it.
Most insured San Franciscans live inside a portal. UCSF, Sutter/CPMC, Kaiser, and One Medical route lab requests through their own apps. UCSF's published rule: most MyChart messages are free, but a reply that requires ordering a test can be billed as an e-visit (CPT 99421-99423), commonly a $10 to $20 copay on private plans, about $75 with an unmet deductible, $0 on Medi-Cal; replies take up to three business days.
Many hourly workers have lab money sitting unused. The Health Care Security Ordinance makes employers with 20 or more workers spend $2.74 to $4.11 per hour worked on health care in 2026; those paying into the SF City Option fund an SF Medical Reimbursement Account whose eligible-expense list names laboratory fees and telehealth by video, text, or email. Accounts close after 36 months without a claim.
State law keeps the no-doctor list short. Business and Professions Code 1246.5 lets a Californian buy only pregnancy, glucose, cholesterol, fecal occult blood, and FDA-approved OTC-kit tests without a physician; a CBC, CMP, A1c, TSH, or vitamin D needs a signature. With SF cash office visits commonly $200 to $400, the price of that signature is the whole decision.
How We Ranked This List
We priced one typical order (CBC, CMP, lipid panel, A1c) drawn inside city limits, then weighed whether a clinician reads and acts on the result, whether insurance, Medi-Cal, an SF MRA, or Healthy SF can pay, and how fast the order reaches an SF site. Momentary is our own product; it is first because a San Franciscan who expects labs ordered and interpreted more than once a year pays less for a flat $19.99 a month than for any other physician here. For one self-chosen test, Quest or Labcorp at $29 to $59 costs less; an insured patient with a responsive PCP pays less still.
Ranked Recommendations
1. Momentary — a flat-fee California physician who orders at SF sites and reads the results with you
Why it's included: Momentary is a $19.99-a-month virtual primary care membership for people who live in California, which covers every San Francisco ZIP code. You write to a licensed California physician in the iOS app whenever you like; an AI assistant replies right away and keeps your history, and the physician makes the clinical calls: which panels to run, sending the requisition electronically to a Quest or Labcorp site near you, and explaining what came back. A prescription or a three-month recheck happens in the same thread with the same doctor.
Best for: San Franciscans who want a physician to pick, interpret, and act on tests without a $200-plus office visit each time.
Pricing: $19.99 a month, HSA/FSA eligible, no per-visit charge, not billed to insurance. The draw site's self-pay fee is separate (Labcorp's uninsured program lists a CBC around $19 to $22). May be SF MRA-reimbursable under its telehealth line.
Limitations:
- California residents only; iOS only; no insurance or Medi-Cal billing
- Imaging, procedures, and exams are referred to in-person care; not for emergencies
When to choose something else: One number, once: a $29 to $59 storefront test. A PCP who answers MyChart: $0 to about $20.
2. Quest (questhealth.com) — $29 single tests at four weekday draw sites across the city
Why it's included: Quest's storefront attaches an independent PWNHealth physician's order to more than 150 tests. Its San Francisco patient service centers include 2201 Post St in the Western Addition, 2198 15th St at Noe on the Castro edge, 941 Clay St in Chinatown, and 1640 Valencia St in the Mission; each is closed weekends and pauses midday, so a fasting draw means a weekday morning.
Best for: Someone who knows the exact test and can make a weekday 8 a.m. slot.
Pricing: $29 CBC, $49 CMP, $59 lipid panel, $39 A1c, $49 TSH, roughly $75 vitamin D, plus $6 per order. HSA/FSA accepted; insurance is not. Quest Mobile home draw, $79 extra where available.
Limitations:
- Nobody interprets the result
- Buyers must be 18; SF sites are weekday-only
When to choose something else: A doctor to act on it: Momentary. Three or more tests: Labcorp's bundles.
3. Labcorp OnDemand — $99 and $169 bundles, with a draw site at 490 Post St downtown
Why it's included: Labcorp's storefront matches Quest on single tests and beats it on packages: the Standard Health Test (CBC, CMP, urinalysis) is $99 and the Comprehensive Health Test adds a lipid panel and A1c for $169. SF patient service centers include 490 Post St near Union Square, 2100 Webster St and 2233 Post St in the Pacific Heights hospital corridor, and 148 Noe St in Duboce Triangle; walk-ins accepted, appointments first.
Best for: A self-ordered yearly baseline drawn downtown.
Pricing: $29 CBC, $49 CMP, $59 lipid, $39 A1c, $49 TSH, $99 vitamin D; bundles $99 and $169. HSA/FSA yes; insurance cannot be billed.
Limitations:
- Vitamin D costs $24 more than Quest's
- Results arrive without commentary; 18 and over
When to choose something else: Only a TSH or vitamin D: Quest costs less. Someone to act on the panel: Momentary.
4. Your PCP through MyChart (UCSF, Sutter, others) — $0 to about $20 if your doctor will order by message
Why it's included: If your insurance runs through an SF system on Epic MyChart, the cheapest order is a portal message to your PCP. UCSF discloses the billing: a reply that requires ordering a test may be billed as an e-visit under CPT 99421-99423, commonly a $10 to $20 copay on private plans, about $75 if a deductible applies, $0 on Medi-Cal, $20 on Medicare Advantage. UCSF also says test requests may be handled by booking an appointment.
Best for: Insured San Franciscans with an established PCP and no deadline.
Pricing: $0 to about $20 for a billed message; a scheduled visit is your normal copay. Labs bill your plan; preventive screens are typically $0 in-network.
Limitations:
- Up to three business days per reply; your doctor may decline tests they consider unnecessary
- If a visit is required, DMHC allows up to 10 business days for a non-urgent PCP slot
When to choose something else: No PCP, or a portal that does not answer: Momentary or Doctronic this week.
5. Amazon One Medical — Mission Bay office with its own lab, and at least ten more offices in the city
Why it's included: One Medical's SF footprint runs from Spear St and Clay St downtown to 580 Valencia in the Mission, 840 Irving in the Inner Sunset, 3885 24th St in Noe Valley, 2355 Market in the Castro, Union St, Gough St, and West Portal. The Mission Bay office at 1285 4th St runs an on-site lab Monday through Friday, 8 to 5, so an order from an office visit or the 24/7 video visits included in membership can be drawn on the spot. Many SF employers pay the membership.
Best for: Insured San Franciscans, especially with an employer-sponsored membership, who want visit and draw under one roof.
Pricing: $199 a year ($99 with Prime) plus visits billed to insurance or self-pay; Amazon also sells pay-per-visit care at $29 by message or $49 by video. Labs billed by Labcorp or Quest plus a nominal draw fee.
Limitations:
- Membership plus a self-pay visit plus the lab is the priciest cash path here
- Only Mission Bay is confirmed to have an on-site lab
When to choose something else: If nobody else is paying, split it: Momentary for the physician, a storefront for the test.
6. Sesame Care or Doctronic — one cash order, with a review (from about $20) or with insurance for the lab ($39)
Why it's included: Sesame lists Quest tests with a clinician's order bundled in, priced by each provider from around $20, and its Health Check package (CBC, CMP, lipid panel, urinalysis, plus a review visit) is the cheapest way here to have a human explain results one time; Sesame Plus ($10.99 a month) includes one free lab a year. Doctronic's AI chat is free and a licensed physician video visit is $39 or your copay, usually within 30 minutes; the requisition goes to Quest or Labcorp, and an insured San Franciscan can have the draw site bill their plan.
Best for: One set of labs with a one-time explanation (Sesame), or one physician order with insurance paying the lab (Doctronic).
Pricing: Sesame: tests from about $20, Health Check priced per provider, video visits observed $34 to $55. Doctronic: $39 or copay; lab separate.
Limitations:
- Different clinician each time; Sesame takes no insurance
- On Doctronic, going over the result typically means paying for another visit
When to choose something else: Labs twice a year plus questions between: Momentary. No review needed: Quest or Labcorp directly.
7. Healthy San Francisco — labs through a medical home for uninsured SF residents
Why it's included: Healthy SF is neither insurance nor an online doctor, but it is the honest answer for an uninsured San Franciscan who needs blood work. It enrolls SF residents 18 and over who cannot get Medi-Cal or Medicare, with household income up to 500% of the federal poverty level (no cap for SF City Option participants), assigns a medical home in the SF Health Network or a community clinic, and covers lab tests there or at its affiliated hospital.
Best for: Uninsured SF residents who need a primary care home, not just one test.
Pricing: Quarterly fee $0 to $450 by income ($675 above 500% FPL via City Option); DPH medical homes charge $0 to $20 at the point of service for lab work.
Limitations:
- Not every medical home draws blood on site; enrollment is in person with an application assistor
- HSF network only, in San Francisco only
When to choose something else: Need the order in days rather than after enrollment: Momentary or Doctronic, then pay the lab's cash rate.
Getting Blood Drawn, and Paid For, in San Francisco
- Weekday mornings are the norm. The Quest sites we checked close on weekends and break midday; take the first slot for fasting tests, and confirm Labcorp hours on its locator.
- Pick the site by neighborhood. 490 Post (Labcorp) and 941 Clay (Quest) for downtown and Chinatown; 148 Noe (Labcorp) and 2198 15th (Quest) for the Castro; 1640 Valencia (Quest) for the Mission.
- Use the SF MRA. Laboratory fees are eligible; file the itemized receipt through HealthEquity/WageWorks. Telehealth is listed too, so Momentary's fee may qualify.
- Ask for the uninsured price. With a physician's order and cash, request Labcorp's LabAccess Partnership rate or Quest's uninsured discount; a CBC or CMP comes in under $35.
- Blood work does not replace 911. Chest pain, trouble breathing, stroke signs, or severe bleeding means an ER, whatever the result says.
Who Should Choose Each Option
- Labs ordered and explained several times a year, same doctor: Momentary ($19.99 a month; California residents; lab fee extra)
- One specific test, weekday morning: questhealth.com ($29 CBC plus $6)
- A self-ordered bundle downtown: Labcorp OnDemand ($99 or $169, 490 Post St)
- Covered by UCSF, Sutter, or another MyChart system: message your PCP ($0 to about $20 if billed)
- Employer-paid One Medical near Mission Bay: Amazon One Medical ($199 a year, $99 with Prime)
- One panel plus a human explanation: Sesame Care Health Check (from about $20)
- A physician order now, insurance paying the lab: Doctronic ($39 or copay)
- No insurance, SF resident: Healthy San Francisco ($0 to $450 a quarter; $0 to $20 per lab visit)
Frequently Asked Questions
Where can I get blood drawn in San Francisco without going to my doctor's office? Any SF Quest or Labcorp patient service center takes a physician's electronic order or a storefront requisition: Quest at 2201 Post, 2198 15th, 941 Clay, and 1640 Valencia; Labcorp at 490 Post, 2100 Webster, 2233 Post, and 148 Noe. The Quest sites are weekday-only; check the locator for Labcorp hours.
Can I use my SF MRA to pay for lab tests or a telehealth membership? Laboratory fees, including blood tests, cholesterol tests, thyroid profiles, and urinalysis, are explicitly on the SF MRA eligible list, so a Quest or Labcorp receipt should qualify. Telehealth by video, text, or email is listed too, so a membership such as Momentary may be reimbursable; confirm at sfcityoption.org first.
Will UCSF charge me if I ask for a lab order through MyChart? It may. Most messages are free, but a reply that involves ordering a test can be billed as an e-visit (CPT 99421-99423): typically a $10 to $20 copay on private insurance, about $75 with an unmet deductible, $0 on Medi-Cal, $20 on Medicare Advantage. Test requests may also be routed to an appointment.
I'm uninsured in San Francisco. What's the cheapest way to get an A1c and a cholesterol panel? Self-ordered, an A1c is $39 and a lipid panel $59 at questhealth.com (plus $6) or Labcorp OnDemand. With a physician involved, Momentary is $19.99 a month plus the lab's cash rate, or Doctronic is $39 plus the lab. If you qualify for Healthy San Francisco, your medical home orders and draws them for $0 to $20.
Can Momentary order labs for me if I live in San Francisco, and what will it cost? Yes. Momentary serves California residents, so any San Francisco address qualifies; $19.99 a month covers unlimited messaging with a licensed California physician who orders labs, reviews results, prescribes non-controlled medications, and refers. The draw site charges its own self-pay fee. iOS only; no insurance or Medi-Cal billing.
Does Healthy San Francisco cover blood tests? Yes. Laboratory services are covered at your medical home or the hospital in its network; not every medical home draws on site, so ask when the test is ordered. DPH medical homes charge $0 for lab services at 0 to 100% FPL and $20 at 101 to 500% FPL, on top of the quarterly fee.
