Common Questions​

Q: Why does the doctor adjust medication even when indicators are within normal range?​

A: Because the normal range is for the general population, individualized treatment needs to consider:

  • Whether symptoms are improving
  • Target TSH value (e.g., post-surgery requires TSH < 0.1)
  • Seasonal changes (winter dosage may need to increase)
  • Pregnancy plans (more strict control needed)

Q: What should I do if TSH fluctuates significantly?​

A: TSH fluctuations may be caused by:

  • Irregular medication intake
  • Inconsistent examination times
  • Different hospital testing result variations
  • Influence from other diseases

Suggestions:

  • Maintain regular medication
  • Get examined at the same hospital consistently
  • Have blood drawn at the same time (e.g., morning)
  • Keep detailed records to consult with your doctor

Q: What if an indicator suddenly becomes abnormal?​

A: Don't panic. First investigate:

  1. Did you take thyroid medication before the examination?
  2. Did you take other medications that affect testing (e.g., biotin)?
  3. Did you change hospitals for testing?
  4. Are there other influencing factors (e.g., pregnancy, infection)?

If confirmed abnormal, consult your doctor promptly.

FAQ​

Q: Why are some data points not displayed on the chart?​

A: This may be because:

  • No record of that indicator exists at that time point
  • Outside the current display time range
  • The indicator is hidden (check the legend)

Q: How do I judge if my condition is stable?​

A: Comprehensive judgment:

  • Indicators within normal range
  • Trend line is stable without major fluctuations
  • Symptoms improved or disappeared
  • Multiple consecutive examination results are consistent

Q: Can chart data be exported as Excel?​

A: Yes. When exporting a report, select Excel format. The exported file can be opened and edited in Excel.

Q: Can I compare my data with family members' data at the same time?​

A: No. One account can only record data for one person. To compare, it is recommended to export data separately and compare manually.
