Analysis Rules (4)

purity

Purity percentage measurement

Created Wed 3 Dec 2025 20:26

JavaScript Code:

function analyze(result, sample, test) {
  // Purity test: ≥99% Pass, <95% Catastrophic, between is Fail
  const value = result.measure_value;
  if (value === null || value === undefined) {
    return "Neutral";
  }
  if (value >= 99) {
    return "Pass";
  }
  if (value < 95) {
    return "Catastrophic";
  }
  return "Fail";
}

endotoxins

Endotoxin test

Created Wed 3 Dec 2025 20:26

JavaScript Code:

function analyze(result, sample, test) {
  // Endotoxins test: Pass if measure_flag is 'Pass' or 'Below LOQ', else Catastrophic
  const flag = result.measure_flag;
  if (flag === "Pass" || flag === "Below LOQ") {
    return "Pass";
  }
  return "Catastrophic";
}

quantity

Quantity measurement in mg

Created Wed 3 Dec 2025 20:26

JavaScript Code:

function analyze(result, sample, test) {
  // Quantity test: within ±10% Pass, ±30% Fail, beyond Catastrophic
  const value = result.measure_value;
  if (value === null || value === undefined) {
    return "Neutral";
  }
  
  let refQty = sample.batch_quantity;
  if (refQty === null || refQty === undefined) {
    refQty = sample.label_quantity;
  }
  
  if (refQty === null || refQty === undefined) {
    return "Neutral";
  }
  
  const lowerPass = refQty * 0.9;
  const upperPass = refQty * 1.1;
  const lowerFail = refQty * 0.7;
  const upperFail = refQty * 1.3;
  
  if (value >= lowerPass && value <= upperPass) {
    return "Pass";
  }
  if (value >= lowerFail && value <= upperFail) {
    return "Fail";
  }
  return "Catastrophic";
}

identity

Identity confirmation test

Created Wed 3 Dec 2025 20:26

JavaScript Code:

function analyze(result, sample, test) {
  // Identity test: Pass if measure_flag is 'Pass', else Catastrophic
  if (result.measure_flag === "Pass") {
    return "Pass";
  }
  return "Catastrophic";
}

JavaScript Data Context

The analyze(result, sample, test) function receives these objects:

result

• .measure_value (number | null)

• .measure_flag (string | null)

• .result_date (string)

• .unit (string | null)

• .notes (string | null)

• .exception (string | null)

• .loq (number | null)

• .method (string | null)

sample

• .batch_quantity (number | null)

• .label_quantity (number | null)

• .registered_date (string)

• .batch_id (string | null)

• .batch_source (string | null)

• .storage_location (string | null)

test

• .tested_date (string | null)

• .coa_date (string | null)

• .coa_url (string | null)

• .coa_id (string | null)

Valid Return Values

• "Pass"

• "Fail"

• "Catastrophic"

• "Neutral"

JavaScript runs in an isolated V8 sandbox. Must define function analyze(result, sample, test).
