Record explicit urine and plasma analyte unit labels without assuming compatible concentration scales.

Description

Record explicit urine and plasma analyte unit labels.

Renal records distinguish spot/daily reporting, urine/plasma units, indexed versus absolute results and session-relative sampling. A label for an indexed value does not perform body-area scaling, while session mass change differs from verified fluid removal. Source definitions and clinical context remain necessary for interpretation.

Record explicit urine and plasma analyte unit labels.

When to use this tool

Use Urine Plasma Analyte Unit Pair when you already have analyteCode, urineUnit, plasmaUnit and need to record explicit urine and plasma analyte unit labels.

How to use the tool and how it works

  1. Enter analyteCode, urineUnit, plasmaUnit. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read token. Use the output convention below.

Enter analyteCode, urineUnit, plasmaUnit using the field constraints below. Encode these values, in exactly that order, as a JSON array and return the serialized array as text in token. String values are preserved without trimming or external terminology lookup.1

Limitations and assumptions

  • The result records supplied values without assuming compatible concentration scales. Sources and asserted relationships are not independently authenticated.
  • 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

Check the original collection, laboratory and session records before combining values. Apply a complete validated measurement or calculation method when conversion beyond the stated units or reference labels is required; do not infer renal function from a local record helper.
