Questions and answers
Why this machine read Glucose high
The AVE-73 Series urine analyzer measures glucose levels using matched urine test strips. High glucose readings could result from actual high glucose concentration in the urine or potential errors such as incorrect test strip usage, expired or contaminated strips, or calibration issues. Additionally, environmental conditions like unstable voltage or incorrect storage of test strips may affect accuracy. The analyzer has a self-checking function to identify faults, so reviewing error messages and performing maintenance may help resolve discrepancies.
