DPD - Deoxypyridinoline (Pyrilinks D)

Individuals at risk for osteoporosis, especially postmenopausal women, those with a family history of bone diseases, and individuals undergoing therapies that can affect bone density, may benefit from the DPD test.

The DPD test is usually performed on a urine sample. The patient is often asked to collect urine over a 24-hour period which is then analyzed for levels of Deoxypyridinoline.

High levels of DPD in the urine suggest increased bone resorption, which may indicate osteoporosis or another bone disorder. Your healthcare provider will interpret the results in the context of your medical history and other tests.

Yes, consuming a diet high in protein or taking calcium supplements can affect DPD levels in the urine. Some medications, including hormone replacement therapy and bisphosphonates, can also affect the results.

Avoid consuming foods high in protein and refrain from taking calcium supplements for 24 hours before the test. Follow any additional instructions provided by your healthcare provider.

The DPD test can be used to monitor the effectiveness of treatment for bone disorders like osteoporosis. A decrease in DPD levels after starting treatment may indicate that the medication is effective in reducing bone resorption.

The DPD test is non-invasive and involves collecting a urine sample, so there are no significant risks associated with the test itself.

The frequency of testing depends on various factors such as your age, risk factors for bone disorders, and whether you are undergoing treatment for a bone disorder. Your healthcare provider will give you specific recommendations.

Other tests that might be done alongside the DPD test include bone mineral density (BMD) tests, blood calcium levels, and other markers of bone turnover like C-telopeptide (CTX).

Factors such as diet, medications, kidney function, and hormonal levels can affect DPD levels in urine.

Yes, other tests such as the N-telopeptide test (NTX) and C-telopeptide test (CTX) are also used to evaluate bone resorption.

Normal values can vary depending on the laboratory that analyzes the test. Generally, lower levels indicate normal bone resorption, while higher levels indicate increased bone resorption.

In case of abnormal DPD levels, it is advisable to consult an endocrinologist or a rheumatologist, who specializes in bone disorders.

Coverage for the DPD test depends on your health insurance plan. It is recommended to check with your insurance provider regarding coverage for this test.

The DPD test is an essential tool for assessing bone resorption and managing bone disorders like osteoporosis. It is particularly important for individuals at high risk of bone loss. By regularly monitoring DPD levels and adhering to the treatment plan, patients can effectively manage their bone health.
