+= UseCase06 - Doctor Requests Lab Test =
+
+== Initiating Actor - `Doctor` ==
+
+
+== Description ==
+A doctor requests a laboratory test for a patient. The system creates a performed lab test record linking the doctor, patient, and the specific test.
+
+== Scenario ==
+
+1. Doctor opens a patient's medical record.
+
+{{{
+#!sql
+SELECT
+  mr.record_id,
+  mr.patient_id
+FROM medical_records mr
+WHERE mr.patient_id = (
+  SELECT patient_id FROM users WHERE username = 'maja.veljanova'
+);
+}}}
+
+2. System displays all available lab tests.
+
+{{{
+#!sql
+SELECT
+  lt.test_id,
+  lt.test_name,
+  lt.description,
+  lt.cost
+FROM lab_tests lt
+ORDER BY lt.test_name;
+}}}
+
+3. Doctor selects a lab test, specifies the test date and notes, and submits the request.
+
+{{{
+#!sql
+INSERT INTO performed_lab_tests (patient_id, doctor_id, test_id, test_date, notes)
+VALUES (
+  (SELECT patient_id FROM users WHERE username = 'maja.veljanova'),
+  (SELECT doctor_id FROM users WHERE username = 'elena.kirova'),
+  (SELECT test_id FROM lab_tests WHERE test_name = 'Complete Blood Count'),
+  '2026-06-05',
+  'Blood work for hypertension monitoring'
+)
+RETURNING performed_test_id;
+}}}
+
+4. System calculates the total cost of lab tests performed on that date for this patient.
+
+{{{
+#!sql
+SELECT SUM(lt.cost) AS total_cost
+FROM performed_lab_tests plt
+JOIN lab_tests lt ON plt.test_id = lt.test_id
+WHERE plt.patient_id = (
+SELECT patient_id 
+FROM users 
+WHERE username = 'maja.veljanova')
+  AND plt.test_date = '2026-06-05';
+}}}
+
+5. System creates a billing record for the patient.
+
+{{{
+#!sql
+INSERT INTO billing (total_cost, payment_status, record_id, admin_id)
+VALUES (
+  75.00,
+  'PENDING',
+  (SELECT record_id FROM medical_records WHERE patient_id = (SELECT patient_id FROM users WHERE username = 'maja.veljanova')),
+  (SELECT admin_id FROM admin LIMIT 1)
+)
+RETURNING bill_id;
+}}}
+
+6. System links the billing record to the performed lab test.
+
+{{{
+#!sql
+INSERT INTO billing_lab_tests (bill_id, test_id)
+VALUES (
+  (SELECT MAX(bill_id) FROM billing),
+  (SELECT test_id FROM lab_tests WHERE test_name = 'Complete Blood Count')
+);
+}}}
+
+7. System confirms the request and displays all pending lab tests for the patient.
+
+{{{
+#!sql
+SELECT
+  plt.performed_test_id,
+  lt.test_name,
+  plt.test_date,
+  plt.notes
+FROM performed_lab_tests plt
+JOIN lab_tests lt ON plt.test_id = lt.test_id
+WHERE plt.patient_id = (
+SELECT patient_id 
+FROM users 
+WHERE username = 'maja.veljanova');
+}}}
