What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

Order vs observation: Observation
Method: DXA

What it does not mean

The code identifies the observation or test, not the actual result.

Key facts

DXA Humerus - left [Z-score] Bone density

Views for bone density

Measuring the bone density of the humerus helps determine the best approach to treatment for patients being considered for shoulder surgery and those with humeral fractures. Patients needing shoulder surgery are at higher risk of local osteoporosis due to lack of mechanical stimulation, and general osteoporosis is a common risk factor for proximal humerus fractures in patients aged 65 and over. Determining the presence of osteoporosis pre-operatively can help decide if different repair techniques and hardware, such as threaded anchors, should be used. [PMID25027108]
