Quick answer
AVA Médica has a clinical lab inside the same clinic where you see the doctor, in Piedras Negras. You can get tests such as glucose, a lipid panel, a thyroid panel, a complete blood count, or a urinalysis, and handle the visit and the test in one trip. The clinic is open every day from 8 am to midnight, no appointment needed. Message us on WhatsApp to confirm your test, its preparation, and its cost.
Most requested tests
- Glucose, to detect or monitor diabetes.
- Lipid panel: cholesterol and triglycerides.
- Thyroid panel.
- Complete blood count, to check for anemia and infections.
- Urinalysis.
If your doctor ordered a test that isn't on this list, send us a photo of the order on WhatsApp and we'll tell you whether we run it here and how much it costs.
Doctor visit and test in the same trip
Having the lab inside the clinic means you don't have to go from one place to another: the doctor examines you, orders the test if it's needed, and you get it done right there. For common concerns like high blood sugar, fatigue that won't go away, or a urinary infection, that means getting answers without losing days.
How to prepare
- Some tests require fasting, such as glucose or a lipid panel (usually 8 to 12 hours). Confirm with us before you come.
- For the urinalysis, we'll explain how to collect the sample.
- If you already have a doctor's order, bring it. If not, start with a visit and the doctor will tell you which tests you actually need.
If you're coming from Texas
Without insurance, blood work in the U.S. can cost several times what it does in Piedras Negras. If you're coming from Eagle Pass, Del Rio, or South Texas, message us before you cross: we'll give you the exact cost and guide you on the Medical Lane at International Bridge #1, which cuts the trip back to the U.S. to about 15 to 20 minutes.
Frequently asked questions
Do I need an appointment for lab work?
No. The clinic takes walk-ins every day from 8 am to midnight. If your test requires fasting, message us on WhatsApp first to confirm the sample collection hours.
How long do results take?
It depends on the test. When we collect your sample, we'll tell you when and how you'll receive your results.
Can I get tests without a doctor's order?
Message us and we'll tell you which tests you can get directly. Even so, it's most useful to start with a visit: the doctor tells you which ones you need and explains the results.
How much does a lab test cost?
It depends on the test. Send us the name of the test or a photo of your order on WhatsApp and we'll give you the exact cost.
