When to Get Lab Testing

Lab testing isn’t only for when you’re feeling sick. Patients come in for lab work at OnPoint for two main reasons: to diagnose a current symptom, or to screen for conditions before they cause problems. 

You Have Symptoms That Need Answers

If you’re experiencing a sore throat, fever, painful urination, fatigue, or other symptoms that haven’t resolved on their own, lab testing helps your provider pinpoint the cause quickly and get you started on the right treatment. 

You Need Testing for Work or School

Certain employment, occupational medicine, or school requirements call for specific lab tests. OnPoint can accommodate most routine testing needs on a walk-in basis.

You Were Exposed to Something

If you’ve had a known or potential exposure to an infectious disease, testing gives you a clear answer so you can take the right next steps for your health and the health of those around you.

The Easiest Way to Get Lab Work Done

Most labs require a separate appointment, a separate trip, and a different provider to explain your results. At OnPoint, your physician orders your tests, your sample is collected on-site, and your results are reviewed in context with your symptoms, all during the same visit at any of our six Denver-area locations.

Walk-in availability seven days a week means you’re not waiting until Monday to get answers, and you’re not navigating a separate referral process just to get basic blood work done. OnPoint accepts most major insurance plans, and self-pay options are available for patients without coverage.
