QUESTIONS TO TAKE WITH YOU

When should you repeat a DEXA scan? Questions to ask

A result in the reference range is one part of your health picture. You do not need to keep scanning simply because the option is available.

Agree on what another scan would answer

Start with the purpose of the first scan. Did it answer the question? If the result did not change the plan, ask what new information a repeat appointment would add. A package expiry or a calendar interval is not, by itself, a clinical reason to test.

For a planned comparison, ask which measurement matters and how much change the facility can reliably distinguish. Keep fat mass, lean tissue and percentages separate. A shift in one percentage does not explain which compartment changed.

Accuracy and repeatability ↗

Check measurement variation

The LSC calculator illustrates how a facility’s precision relates to a comparison threshold. Use it as a question to take to the clinic, not as a diagnosis or proof of progress.

Is the change larger than measurement variation?

Use the same measure, units, scanner and comparable preparation. The 2% starting value is an educational lean-mass example, not your clinic’s measured precision. For fat mass, the ISCD minimum acceptable precision example is 3%. Replace this with the clinic’s own precision or ask for its LSC directly.

Enter positive values to calculate an illustrative threshold.

This approximation converts relative precision using the first value. An exceeded threshold is not proof of muscle gain, fat loss or a clinically important change. Hydration and protocol differences still matter. Values stay in your browser.

Keep reports and preparation together

Save the full report, including manufacturer, software, scan date and region definitions. Note anything different about the preparation. The private tracker can hold a short record, but it cannot replace those original files.

Once a follow-up date has been agreed, download a calendar reminder. It does not book an appointment, choose a rescan interval or send measurements to us. The calendar you use controls notifications.

Repeat-scan preparation ↗

At your appointment

  1. Did this scan answer the question I had?
  2. Is there a practical reason to repeat it?
  3. What should I track between appointments?

A sensible next step

Keep the report. If you and your practitioner decide to repeat the scan, agree on the purpose and preparation before booking.

These suggestions are general information. Your own practitioner can review the full report and your history.
