+# Laboratory Service Requests by Patient Count - SSMM
+
+> Number of completed laboratory service requests per patient per day.
+
+## Purpose
+
+Identifies patients with the highest volume of laboratory service requests at SSMM. 
+
+## Parameters
+
+*No parameters — the query returns all completed laboratory service requests.*
+
+---
+
+## Query
+
+```sql
+SELECT 
+    DATE(sr.created_date) AS created_date,
+    p.name AS patient_name,
+    pi.value AS ssmm_id,
+    COUNT(*) AS request_count
+FROM emr_servicerequest sr
+JOIN emr_patient p ON sr.patient_id = p.id
+LEFT JOIN emr_patientidentifier pi ON p.id = pi.patient_id AND pi.config_id = 21
+WHERE sr.status = 'completed'
+  AND sr.category = 'laboratory'
+GROUP BY DATE(sr.created_date), p.name, pi.value
+ORDER BY request_count DESC;
+```
+
+
+## Notes
+
+- Only service requests with `status = 'completed'` and `category = 'laboratory'` are counted.
+- **Hardcoded values:**
+  - `pi.config_id = 21` — the identifier config representing the SSMM ID. Update if the config ID changes.
+  - `sr.category = 'laboratory'` — restricts to lab requests; change to widen/narrow the scope (e.g. `'imaging'`).
+- Results are ordered by highest `request_count` first, so top lab consumers surface at the top.
+- No date filter is applied — the result spans all history. Add a `[[AND {{created_date}}]]` clause if a Metabase date filter is needed.
