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.

Greeted immwdiatly when I walked thru the door and proceeded to the exam room within five minutes. The staff introduced themselves to me as soon as we met walking in the door. Katie, the physicians assistant, awesome PA!! Very knowledgeable, had great “ bedside manner.” Ask more questions about my medical history and then dealled into what she felt we needed to get into today. Truly felt comfortable with everything that happened from the time I walked through the door to the time I walked out the door. Highly highly recommend this office and staff. Thanks for a wonderful visit! Bobbie. Cantu

Wait time was unexpectedly long! I was there for one hour and 15 mins for an EKG the order was sent the day before so that was not the problem. Was called 15 mins after my scheduled appt and there was only one other person in the waiting room when I was called. Also when I arrived there was one person ahead of me. Provider was very good and staff friendly. The assistant who who performed the EKG was great knowledge about the procedure. After the procedure I had a wait again another 15 mins.

Why did you close the Montclair site? Open only on Wednesday for dermatology? Not good. People need urgent care. Not once a week. Open back up

y friend told me to look for Joan because they say she is very helpful. When i came in the office i look for her right away. I waited for her to assist me so i can introduce me. I'm so glad that there is a filipina in front desk now No more having a hard time talking with two other rude front desk! especially the white girl who does not have respect to older patients. Joan is the only one i found that is a nice young lady very polite explains briefly, carefully also listens very well with complete details also is very patience specially with old patient like us; the clinic need more like her. I appreciate all of her help to me i can see that she is the only one working hard when i went to office the other two r just chitchatting and loud
