What This Entry Represents

The slug describes a transferring facility—the healthcare location that sends a specimen, sample, or patient to another facility for testing or care. In laboratory and health records, this is typically captured as structured administrative data so that results and specimens can be traced accurately.

Why It Matters in Records

Recording the transferring facility helps maintain a clear chain of custody and supports accurate reporting, billing, and result routing. It also allows clinicians reviewing a result to understand the origin of the specimen and the context in which it was collected.

What It Is Not

This is not a test for a specific analyte such as glucose, cholesterol, or a hormone, and it does not produce a numeric result. There is no specimen type, measurement method, or reference range associated with it.

How It Is Used

Facilities and laboratories use this type of field in electronic health records and laboratory information systems to support quality tracking, regulatory reporting, and coordination of care between sites.

Reference range

NCBI: Transferrin 200-350 mg/dLN/A

Specimen: serum

Fasting for 12 hours preferred. Iron supplements should be stopped 24 hours before if possible.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Is a transferring facility a lab test?
No. It is an administrative or documentation entry that records which facility sent a specimen or patient, not a clinical measurement.
Will this appear on my lab report?
It may appear as identifying information on requisitions or reports, especially when a specimen is sent between sites, but it is not a result value and has no reference range.
Does this information affect my results?
It does not change the analytical result itself, but accurate documentation helps ensure the correct specimen is linked to the correct patient and site, which supports reliable reporting and care coordination.
