Project Structure

The contract follows a modular design with separate files for state management and business logic (instructions/contexts).

1️. Account Structures

These define data storage on Solana.

• patient_data.rs – Stores patient details and lab test history in a PDA.
• test_result.rs – Defines the structure for individual test records, including Blood, Urine, and Imaging tests.

---

2️. Instructions

These handle transactions and interactions with the smart contract.

• initialize_patient.rs – Creates a new patient account (PDA) using a Unique Patient ID (UPID).
• store_test_results.rs – Allows authorized labs to store patient test results on-chain.
• get_test_results.rs – Fetches a patient’s medical history securely.
