Description
Compare supplied recorded sterile-lot expiry and evaluation dates.
Clinical and training records can preserve source-qualified point names, study design codes, device wording and reported hours. A record token does not identify an anatomical point or establish treatment effectiveness, and a printed expiry-date gap does not verify sterility or equipment suitability.
Compare supplied recorded sterile-lot expiry and evaluation dates.
When to use this tool
Use Acupuncture Sterile Lot Expiry when you already have asOfDate, recordedExpiryDate and need to compare supplied recorded sterile-lot expiry and evaluation dates.
How to use the tool and how it works
- Enter asOfDate, recordedExpiryDate. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedCalendarDays. Use the output convention below.
Parse real UTC dates; return expiry-asOf calendar days with signs preserved.1

}Limitations and assumptions
- A date gap does not establish sterility, package integrity, authentic manufacture, appropriate equipment or safe/authorized treatment.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Use original clinical, research, training and manufacturer records with the appropriate professional assessment. Local labels and calendar arithmetic do not guide treatment, locate points, select devices, establish efficacy or verify safe practice.
