Why Diagnostic Testing Matters
A large share of medical decisions rely on laboratory or imaging results. From routine blood work during an annual physical to advanced imaging for complex conditions, diagnostic testing helps physicians detect disease early, choose the right treatments, and monitor progress over time. Choosing a reliable, convenient diagnostic provider can make a meaningful difference in your healthcare experience.
Allentown is well served by both national laboratory companies and regional providers connected to the Lehigh Valley's major health networks. Many offer early morning hours, online appointment scheduling, and digital results delivered through patient portals.

How to Choose a Diagnostic Provider
First, check which labs are in-network with your insurance, since out-of-network testing can be expensive. Ask your physician which lab they prefer, because some providers have direct electronic connections that speed up results. Consider location, hours, and whether appointments are available to minimize waiting.
For imaging, ask about equipment quality, radiologist credentials, and accreditation. If you need multiple tests, choosing a provider connected to your health network can make coordination easier.
Diagnostic Trends in the Lehigh Valley
At-home testing and sample collection are becoming more common. Artificial intelligence is helping radiologists detect subtle findings in images. Genetic testing and precision medicine are expanding treatment options, and patient portals now deliver results faster than ever, empowering patients to take an active role in their care.
Frequently Asked Questions
Do I need an appointment for blood work?
Many labs accept walk-ins, but scheduling an appointment online usually reduces your wait time, especially in the early morning when fasting tests are common.
How quickly will I receive my results?
Routine blood test results are often available within one to three days, while specialized tests may take longer. Many results appear in patient portals as soon as they are finalized.
Can I order lab tests without a doctor?
Some national labs offer consumer-initiated testing for certain panels, but reviewing results with a healthcare provider is always recommended.
Preparing for Your Lab Visit
A little preparation can make your visit faster and your results more accurate. Confirm whether your test requires fasting, which usually means no food or drinks other than water for eight to twelve hours. Stay well hydrated, since it makes blood draws easier. Bring your photo identification, insurance card, and lab order if your physician provided a paper copy. Wear a short-sleeved shirt or loose sleeves, and let the phlebotomist know if you feel faint around needles. For imaging appointments, ask whether you should avoid jewelry, metal accessories, or certain medications beforehand.
