If you need a straight answer fast, a blood pregnancy test is the most reliable way to get one. At Advance Medical Lab in Mission, you can walk in without an appointment — and without a doctor's order — and have a qualitative hCG blood test run in our own lab, with results usually ready in about an hour.

The two kinds of blood pregnancy tests

Both tests look for hCG (human chorionic gonadotropin), the hormone your body produces in early pregnancy. The difference is what they tell you:

  • A qualitative hCG test gives a clear yes-or-no answer: pregnant or not. We run this test in-house, and results are usually ready in about an hour — often while you wait or by the time you get home.
  • A quantitative hCG test (often called a "beta hCG") measures the exact level of hCG in your blood. Doctors use it to estimate how far along a pregnancy is or to track whether levels are rising as expected. This test is performed at our reference laboratory, and results typically take about 24 hours.

If you just need to know, the qualitative test is usually the one you want. If your doctor asked for numbers, that's the quantitative test — bring the order if you have one, though you can also request it yourself.

Blood test vs. home pregnancy test

Home urine tests are convenient, but blood tests can detect lower levels of hCG, which means they can often confirm a pregnancy earlier — generally a few days before a home test would turn positive. A lab result also removes the second-guessing: no faint lines, no wondering if you tested too early.

Many patients come to us for exactly that reason — to confirm what a home test suggested, or to settle an unclear result.

Do I need a doctor's order?

No. Texas allows you to order lab tests for yourself, including pregnancy tests, and pay out of pocket — no appointment with a doctor first. If you want to use insurance instead, here's how that works.

What to expect

Walk in Monday–Friday 7:00 AM–8:00 PM or Saturday 8:00 AM–12:00 PM — no appointment needed. Bring a photo ID. The draw itself takes a few minutes. No fasting is required for a pregnancy test.

Your results are confidential and protected under HIPAA, like all lab results.

Common questions

How early can a blood test detect pregnancy?

Blood tests can typically detect hCG earlier than home urine tests — often around the time of a missed period, and sometimes a few days before. If you test very early and the result is negative but your period doesn't come, your doctor may suggest retesting a few days later.

How fast will I get results?

Qualitative (yes/no) results are usually ready in about an hour. Quantitative (beta hCG) results typically take about 24 hours since that test runs at our reference laboratory.

How much does it cost?

Call us at (956) 581-5555 for current self-pay pricing — it's less than most people expect, and you don't need insurance.

Is everything confidential?

Yes. Your results are released only to you (and to a provider you direct them to), and they're protected health information under HIPAA.
