MRD Baseline

 Important

MRD products and their corresponding fields are still hidden from the production API. The documentation is already live here to assist partners during the testing phase.

Myriad Precise MRD™ Baseline is the initial test in the Molecular Residual Disease (MRD) testing workflow. It establishes a molecular baseline for a patient's tumor, enabling subsequent monitoring orders to track treatment response over time.

Key Fields

products: [{ product: MRDBASELINE }] — selects the MRD Baseline product
specimens.mrdblood — MRD blood specimen with collection ownership and hospitalization details
- initialCollectionOwner — who manages the initial sample collection of this baseline order (MYRIAD or PROVIDER)
- futureCollectionOwner — who manages future monitoring sample collections (MYRIAD or PROVIDER)
- collectionDate - the date the initial sample is collected
- hospitalizationCode — patient's hospitalization status (HOSPITAL_INPATIENT, HOSPITAL_OUTPATIENT, NON_HOSPITAL_PATIENT)
- hospitalDischargeDate — required when hospitalizationCode is HOSPITAL_INPATIENT
clinical.monitoringSequence — how frequently monitoring should occur. Options include:
- EVERY_4_WEEKS, EVERY_6_WEEKS, EVERY_8_WEEKS
- EVERY_3_MONTHS, EVERY_6_MONTHS, EVERY_12_MONTHS
- SINGLE, RECOMMENDED, NONE
- RECOMMENDED_NEOADJUVANT_MONITORING, RECOMMENDED_ADJUVANT_MRD_AND_MONITORING, RECOMMENDED_SURVEILLANCE
clinical.plannedSurgeryDate — the date surgery is planned for
clinical.treatmentTimepoint — when clinical data was collected (ADJUVANT, METASTATIC, NEOADJUVANT, SURVEILLANCE, OTHER)
