The acquired full AccessGUDID release records 586 published device records linked to FDA product code IZO. Compare their recorded field relationships below when planning a portfolio mapping. The counts describe this dated public corpus, not unique product models, market size, demand, approval or a test requirement for your device. The source also contains 2 primary-DI owners with resolved package chains of two or more levels. The worked examples below separate each recorded package quantity from the base-package device count and retain atypical endpoints for reconciliation.

What does this dated public cohort contain?
586Published device records
0Parsed device count above one
0Device count missing or unresolved
These are primary-DI record counts, not unique model counts or market size. A DI can be linked to more than one product code, so code cohorts must not be added as unique devices.
| Recorded indicator | True | False | Blank/missing | Unrecognized |
|---|
| Packaged as sterile | 0 | 0 | 586 | 0 |
|---|
| Sterilization required before use | 0 | 0 | 586 | 0 |

| Expiration-date indicator | 26 | 0 | 560 | 0 |

A blank flag is unknown. A true indicator is a recorded label-data fact; it is not a validation report, FDA approval or a test obligation for your product.
Compare the two sterility questions independently
| Packaged as sterile | Sterilization before use | Recorded devices |
|---|
| missing | missing | 586 |
These distinct questions describe the supplied device and user instructions. Review the exact FDA field relationship; do not infer a manufacturer’s validated process from these flags.
Source, filters, reconciliation and limitations
Join acquired full-release device.txt to distinct productCodes.txt relationships by exact PrimaryDI; filter exact FDA code and Published device-record state. Count each DI once within that code. Interpret only literal true/false; blank and unrecognized values remain separate. Parse a positive integer deviceCount for the greater-than-one indicator. Do not apply saved daily updates.
Excluded/unresolved recorded states: {}. Global source-relationship exclusions: {}.
Recorded identities/flags only. Not unique product models, market size, demand, approval, validated sterility, a compliance rate or a mandatory test plan. One DI can occur in several different code cohorts; overall cohort counts must not be added as unique devices.

These worked examples come from this exact product-code cohort. Use their mapping steps to check your own controlled labels and drawings. Keep the public source facts separate from your portfolio.
GUDID records production-identifier flags, rather than actual lot, serial or date values. [12]
The guidance describes a separate unit-of-use relationship for an individual device when the base package contains more than one device and the individual unit does not carry its own UDI label. [13]
Device Count counts devices in the base package. Contains DI Package identifies the lower package level; Quantity per Package counts packages inside that particular configuration. Keep these fields separate. [14]

Selection, computation and source limits
Use the existing checksum-matched full release and exact-code device/product-code cache. Project literal identifier rows under their recorded PrimaryDI owner. Follow Package containsDINumber only within that owner and at most sixteen links. Preserve missing, ambiguous, cyclic and non-Primary endpoints; do not infer or repair them. Count one primary-DI owner per code. Package quantity counts packages at the next recorded level; it is not inferred from deviceCount and no total-unit calculation is performed. PI pairs count literal field states, not individual lot/serial/date values. At most three distinct mapping patterns with no more than twelve literal identifier rows per owner. Prefer atypical package endpoints, then deeper resolved package chains, then multi-device base packages with unit-of-use identifiers, then descending PrimaryDI. Full cohort counts include all published exact-code owners.
Package endpoints: {'Primary': 25}. Quantity states: {'positive-integer': 25}.
These are literal relationships in a dated public full release. Daily updates are not applied. A package or device distribution field is a recorded status, not current stock or provider availability. Unknown, ambiguous or atypical relationships need reconciliation; none establishes a breach. The examples are not prescribed label designs, validated quantities, approval, regulatory equivalence or facts about the buyer.
