You Don't Always Have to Wait for Your Doctor to Get a Health Test

For years, many older adults learned to think of medical testing in a fairly simple way:

See your doctor. Ask about a problem. Get an order. Go to the lab. Wait for the results.

That system still exists.

But healthcare has quietly changed.

Today, there are more ways to get certain health tests, screenings and medical advice without making a traditional doctor's appointment first.

And many older adults may not realize just how accessible some of these options have become.

You may have more options than you think

Some companies now allow consumers to purchase certain laboratory tests online.

Depending on the test and where you live, you may be able to order a blood test online, have an appropriate healthcare professional review the order, and then visit a laboratory to provide the sample.

There are also tests that can be performed at home.

The FDA says home-use tests can help detect or monitor certain conditions, including some cholesterol, hepatitis and glucose testing. But the FDA also emphasizes that home tests shouldn't replace regular medical care and that results often need to be interpreted alongside your medical history, examination and other information.

Then there's telehealth.

Medicare Part B currently covers certain telehealth services, including services that can be provided from your home. Medicare's current policy allows covered telehealth services from anywhere in the United States, including your home, through December 31, 2027.

That means a healthcare conversation that once required a trip to the doctor's office may sometimes begin with your phone or computer.

Medicare covers more preventive screening than many people realize

There's another piece of the puzzle that is easy to overlook.

Medicare Part B covers a broad range of preventive services and screenings.

Depending on your age, sex, medical history and risk factors, these can include cardiovascular disease screening, diabetes screening, colorectal cancer screening, bone-density testing, lung-cancer screening, hepatitis screening, prostate cancer screening, mammograms and other preventive services.

Most covered preventive services cost nothing when you use a provider who accepts Medicare assignment.

And Medicare provides a particularly useful tool that many people don't take full advantage of: the yearly Wellness visit.

It's not a traditional physical exam. Instead, it's a conversation about your health risks and prevention, resulting in a personalized prevention plan.

That can be a good starting point for figuring out what you actually need to be tested for.

But here's the catch

Greater access to testing doesn't necessarily mean more testing is better.

In fact, this may be the most important thing to understand.

Suppose you order a test simply because you can.

The result comes back slightly outside the normal range.

Now what?

You might need another test.

Then another.

You might end up with additional appointments, imaging or procedures—or simply a lot of anxiety over something that turns out not to be clinically important.

That's why an important question isn't simply:

"Can I get this test?"

It's:

"What will we do with the information if the result is abnormal—or normal?"

Medicare itself recommends asking questions such as whether you actually need a test, what it's for, what its benefits and risks are, whether a referral is required, what the results will tell you, and what happens afterward.

Not every test works the same way

There's an important distinction between screening, diagnostic testing and consumer testing.

Screening looks for a disease or condition before you have symptoms. Medicare covers many evidence-based screening services for eligible beneficiaries.

Diagnostic testing is generally used because you have symptoms or because a healthcare professional suspects a particular condition. Medicare covers medically necessary diagnostic laboratory tests when ordered by your healthcare provider.

And diagnostic imaging—such as CT scans, MRIs, X-rays and PET scans—generally requires a healthcare provider's order when Medicare is paying for it.

Consumer testing is testing you seek out yourself. Some blood and home tests fall into this category.

The rules, costs and medical usefulness can be very different between these categories.

A surprisingly good place to start

If you're over 65 and haven't thought about preventive testing recently, you don't necessarily need to start by searching the internet for every test available.

Start with something much simpler:

Ask your healthcare provider:

"Based on my age, family history and health, what preventive screenings should I be getting—and am I up to date?"

Then ask:

"Are there any tests you think would actually change what we do?"

That second question is particularly useful.

A test is most valuable when the answer can lead to a sensible action.

The bigger change in healthcare

The interesting thing isn't that you can now order certain blood tests online.

It's that the walls around healthcare are gradually coming down.

Telehealth can eliminate some trips to the doctor's office.

Home tests can put certain measurements in your own hands.

Online lab services can make some blood testing more accessible.

And Medicare provides a substantial menu of preventive screenings for eligible older adults.

The challenge is no longer simply getting access to information about your health.

It's learning how to use that information wisely.

You don't need to test everything.

You need to know what's worth knowing.

And increasingly, you have more ways to find out.
