Urgent care is a healthcare service focused on providing immediate, non-life-threatening medical attention. Urgent care centers treat conditions such as sprains, cuts , burns , and common illnesses and offer a range of services, including diagnostic and preventive care like immunizations and physicals . With an estimated 15,000 clinics in the U.S., urgent care centers operate beyond traditional primary care office hours, offering a convenient and lower cost alternative to emergency rooms for urgent but minor health issues.

What is a walk-in clinic?

A walk-in clinic is a type of healthcare facility that provides medical care to patients without the need for an appointment. These clinics cover a range of services such as urgent care, occupational medicine, and primary care with walk-in availability. They cater to non-emergent health issues, offering a convenient option for accessible medical attention. Walk-in clinics vary from free services provided by government, charity, or foundation-operated facilities to private clinics with affordable rates, serving as a practical alternative for minor illnesses and injuries outside of traditional doctor's offices and emergency rooms.

Do urgent care centers in Castro Valley take appointments?

Historically, urgent care centers were strictly an on-demand, walk-in healthcare service. More recently, as consumer behaviors and expectations have evolved, many urgent care clinics have begun offering book ahead visits, allowing consumers to select a same-day or next-day time that works best for their schedule. Use Solv to find a Castro Valley urgent care center that offers advanced bookings (or appointments) and book online.

Are Castro Valley urgent care centers open after hours?

Yes. Most primary care doctor offices are open during routine work hours, Monday thru Friday, 9:00 am to 5:00 pm. Conversely, most of the urgent care centers in Castro Valley are available after hours, on weekends, and many holidays. Typical urgent care hours are 8:00 am to 8:00 pm daily, although location-specific hours may vary.

How much will an urgent care visit in Castro Valley cost?

The cost of a visit to an urgent care in Castro Valley varies, with cash prices for the base visit generally ranging from $100 to $175. Additional treatments, such as lab tests, X-rays, or immunizations, can increase costs, typically between $50-150 each. If you're using insurance, expect a co-pay between $20 and $50, depending on your plan and whether the clinic is in-network. Prices differ based on location, so it's best to check directly with the urgent care center and your insurance provider for accurate cost estimates.

I needed to see a clinician to rule out an ear infection; I had been experiencing symptoms of a cold (blocked ears and ringing in the ears) for several days. I have Tricare, which sent me to this facility. I arrived just before 9:00 on Saturday morning and was asked to fill out easy paperwork right away. I was seen maybe 15 minutes after that. The doctor was personable. He diagnosed me quickly and ordered two prescriptions. The whole thing took less than an hour. I’d highly recommend this facility.

Terrible that’s it takes 2 hrs to check in be tested and be seen…. And this is every time I come here. Today my 1 yr old daughter was being seen and though the service is great… protocol to take your toddler out of the car to check in , wait to be told to go back to the car with your toddler and wait again for tests… and then wait again for test results!! Then be called in to wait again for vitals then wait again for the doctor.., to do all this with a toddler is absolutely impossible that my only complaint

1. Sign up/Sign in and Covid test done in a fairly hassle free manner. 2. Jennifer the kind lady who checked me in was super sweet, put my mind at ease and also indulged in having my little one get her BP checked cuz she was soooo curious lol. She earns most of the stars in my review :) 3. The provider I met, Kellie was also easy to talk to and her experience showed well through her diagnosis. The in-clinic treatment provided definitely took away some of my pressing concern. 4. All in all, I’m happy I’ve found a good urgent care so close to home. Amazing though my first experience was, I do hope I won’t be seeing them too frequently..lol!!

I liked the office staff, assistants and doctor I saw. They listened well and showed respect for me, and they were extremely helpful. My only concern--and this is not a criticism of them--is that the center does not have some of the instruments needed to fully assess the medical condition I was presenting.
