Questions people in Houston ask us
Every one of these gets asked on the phone daily. No judgment, just answers.
Do I need a doctor's order to get blood work?
No - the physician order is included with your purchase. You choose the panel, order online, and walk into the test center. If a number needs a doctor's attention afterward, you can share the results PDF with any physician you choose.
Do I need to fast before my test?
Depends on the panel - each product page says clearly before you buy. If fasting is required, it's typically 10-12 hours with water only. Most people fast overnight, get drawn at opening, and have breakfast on the way out.
Do you take insurance?
We don't bill insurance - and that's why the price you see is the entire price. No draw fees, no physician fees, no surprise bill six weeks later. Many customers pay with HSA/FSA cards; check with your plan administrator on eligibility.
How do I get my results?
They post to your secure online account, usually in 1-2 business days. Nothing is mailed to your house, nothing goes to an employer or doctor unless you send it. You can download the PDF and share it with anyone you choose.
How often should I retest?
Once a year as a baseline; every six months if you're actively working on something - cholesterol, thyroid dosing, weight. Trends beat snapshots: the second draw is where the real information starts.
I'm fasting for my panel — how early can I get drawn in Houston?
Many centers open at 6:30 or 7:00 a.m., which means you can fast overnight, be drawn at opening, and eat breakfast on the way to work. Order online the night before so the visit is just a sign-in and a draw.
