What Bone Density Testing Measures and Why It Matters

Bone density testing, also called a DEXA scan or DXA scan, measures how much mineral is packed into your bones. Think of bone like a sponge — it has solid parts and spaces inside. As people age, especially women after menopause, those spaces can get bigger and the solid parts can get thinner. This makes bones more likely to break from a fall or even a minor bump. A bone density test shows whether your bones are strong, normal, or weaker than they should be.

The test uses X-rays, similar to what dentists use, but in a much smaller amount. You lie on a table for about 10 to 30 minutes while a machine scans your lower spine, hip, and sometimes your forearm. The machine doesn't hurt, and you don't have to remove your clothes. The results come back as a number called a T-score, which compares your bone density to that of a healthy 30-year-old person.

According to the National Osteoporosis Foundation, about one in three women over age 50 will break a bone because of osteoporosis, a condition where bones become fragile. For men, the number is about one in five. Bone density testing can catch weakening bones before a break happens. This matters because broken hips, wrists, and spines can lead to long-term disability, loss of independence, and other serious health problems.

Different types of tests exist beyond the standard DEXA scan. Peripheral devices can scan your wrist or heel and take just a few minutes. Some newer tests, like high-resolution CT scans, provide even more detail about bone structure. Understanding what each test measures helps you know which option might work for your situation and health history.

Practical takeaway: Bone density testing is a quick, painless way to learn about your bone strength. The results help you and your doctor understand your risk for broken bones and plan next steps if needed.

Who Should Consider Bone Density Testing

The U.S. Preventive Services Task Force suggests that all women age 65 and older should have a bone density test. For women between ages 50 and 64, the recommendation depends on your individual risk factors. Men age 70 and older should also be tested. However, younger people with certain risk factors may benefit from testing too.

Risk factors that suggest you might want a bone density test include a family history of osteoporosis or broken bones, especially a parent who broke a hip. Personal history matters as well — if you've already had a broken bone from a minor fall, that's a sign your bones may be weaker than expected. Certain medical conditions increase bone loss, including rheumatoid arthritis, kidney or liver disease, cancer, and digestive problems that affect how your body absorbs nutrients.

Medications can also affect bone density. Long-term use of corticosteroids, which treat conditions like asthma and lupus, can weaken bones. Some cancer treatments and certain medicines for seizures have similar effects. If you take any of these medications regularly, your doctor may recommend testing even if you don't have other risk factors.

Lifestyle factors matter too. People who smoke, drink heavy amounts of alcohol, or get very little exercise have weaker bones on average. Women who went through menopause before age 45, either naturally or because of surgery or medical treatment, lose bone density faster than others. Men with low testosterone levels face similar risks. Some people have low body weight, which means less stress on bones and slower bone building.

Practical takeaway: You don't have to be a certain age to think about bone density testing. Review your own health history, family background, and lifestyle to determine whether learning about your bone strength makes sense for you right now.

Types of Bone Density Tests and How They Work

The DEXA scan is the gold standard for bone density testing. It uses two beams of X-rays at different energy levels to measure bone mineral density. The test scans your lower spine and hip because these areas are most likely to break from osteoporosis. The machine takes pictures while you lie still, and a computer analyzes the images. Results typically come back within a week. DEXA scans expose you to a very small amount of radiation — much less than a regular chest X-ray — so the radiation risk is minimal.

Quantitative ultrasound is a different approach that uses sound waves instead of X-rays. A technician puts gel on your skin and presses a wand against your heel, shin, or kneecap. The device sends sound waves through the bone and measures how fast they travel. This test takes only a few minutes and requires no radiation. However, it's less precise than a DEXA scan and typically isn't recommended as the primary way to diagnose osteoporosis, though it can help identify people at risk.

Peripheral DEXA scans are smaller versions of the standard DEXA that measure bone density in your forearm, wrist, or heel. These machines are portable and can be found in some doctor's offices, pharmacies, and health fairs. They're faster and less expensive than full-body DEXA scans, but they may not provide enough information to make treatment decisions on their own. Some people use them for initial screening, then follow up with a full DEXA scan.

High-resolution peripheral quantitative CT scans, called HR-pQCT, take detailed three-dimensional pictures of bone structure. This test can show not just how dense bones are, but also how they're organized inside, which affects strength. These scans are more detailed than DEXA but use more radiation and cost significantly more. They're typically used in research settings or for specific medical questions rather than routine screening.

Practical takeaway: DEXA scans are the most common and reliable choice for most people. Talk with your doctor about which test makes sense for your situation, depending on your age, risk factors, and the information you need.

Finding Bone Density Testing Near You

Bone density testing is available through many types of medical facilities. Large hospitals almost always have DEXA machines in their radiology departments. Many smaller hospitals and imaging centers have them as well. You can start by contacting your primary care doctor, who can order the test and may have recommendations about where to go. Your doctor's office may even have a relationship with a specific imaging center, which can make scheduling easier.

Community health centers and urgent care facilities sometimes offer bone density testing or can refer you to a place that does. Some rheumatologists, endocrinologists, and orthopedic doctors have DEXA equipment in their offices. Aging services offices in your county may have information about testing locations in your area, especially if you're looking for options that serve older adults.

To find testing locations near you, start with an online search for "DEXA scan near me" or "bone density testing near me" followed by your city and state. The International Society for Clinical Densitometry maintains a searchable database of certified imaging centers on their website. Insurance company websites often have provider directories where you can search for imaging centers that accept your insurance plan.

Cost varies depending on location and your insurance coverage. If you have health insurance, your plan may cover part or all of the cost, especially if your doctor orders it based on your age and risk factors. If you don't have insurance or need a cash price, call several centers to compare costs before scheduling. Some imaging centers offer discounts if you pay in cash upfront. The average cost without insurance ranges from $100 to $300, though some centers charge more and others less.

Practical takeaway: Start with your primary care doctor to get an order and recommendations. Use online directories and insurance tools to compare locations, hours, and costs in your area. Call ahead to confirm that the facility accepts your insurance and ask about wait times.

What to Expect During Your Bone Density Test

Preparation for a bone density test is minimal. You can eat and drink normally before the test. Wear loose, comfortable clothing without metal buttons, zippers, or snaps, since metal can interfere with the X-ray images. Remove any jewelry, especially if it's in the area being scanned. Let the technician know if you might be pregnant or if you've had any imaging tests using contrast dye within the past week, since that can affect results.

When you arrive, you'll check in and fill out a health history form. Tell
