Description
Label a specimen with supplied gestational days and dating source.
Maternity records distinguish estimated dates, recorded gestational age, postpartum calendar time and linked maternal/infant identifiers. Completed weeks plus remaining days is a representation of supplied days, not a dating estimate. Image planes, channels and birth-order labels depend on verified clinical records and source conventions.
Label a specimen with supplied gestational days and dating source.
When to use this tool
Use Obstetric Sample Gestational Day Tag when you already have specimenId, suppliedGestationalDays, datingSource and need to label a specimen with supplied gestational days and dating source.
How to use the tool and how it works
- Enter specimenId, suppliedGestationalDays, datingSource. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read label. Use the output convention below.
Require specimenId/datingSource nonempty and nonnegative safe whole gestational days; format specimen; gestational day=N [source].1

}Limitations and assumptions
- Age is recorded rather than estimated; no sample adequacy, dating validity or appropriate care is determined.
- 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.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Consult the original dating, visit, imaging and birth records for a substantive question. Preserve each estimate's source and measurement convention; local date differences and labels do not choose a pregnancy date or assess maternal/fetal health.
