| Request creation (wizard) | Working | 4-step wizard, multi-pricing, insurance, packages |
| Sample tracking | Working | Barcode, collect, receive, reject, bulk operations |
| Result entry | Working | Enter → Validate → Approve → Release pipeline |
| Kanban board | **Just redesigned** | Multi-section, date nav, smart barcode, rich cards |
| Invoicing | Working | Draft → Post → Cancel lifecycle |
| Payments | Working | Cash/card/bank, daily summary, void |

### Catalog/Masters (Complete)
| Area | Status |
|------|--------|
| Sections | CRUD with head info |
| Investigations | CRUD with normal ranges, panels, pricing |
| Specimen types | CRUD |
| Investigation categories | CRUD |
| Packages (test bundles) | CRUD |
| Patients | CRUD with insurance, medical history |
| Doctors | CRUD with commission rules |

### Financial (Good Coverage)
| Area | Status |

| Insurance contracts | Per-test approved price, share split |
| Insurance invoicing | Monthly aggregation |
| Doctor commissions | Calculate + settle |

### Quality & Compliance (Solid)
| Area | Status |
|------|--------|
| QC lots | Levey-Jennings charts |
| Reagent tracking | Stock, batches, consumption |
| Machines/analyzers | CRUD |
| Audit logs | Full change tracking |
| Custody logs | Chain of custody |
| Retention policies | Configurable |

### Reports (6 reports)
Workload, TAT, Revenue, Abnormals, QC Summary, Test Volume — all with date/section filters.

## What's Missing vs Top LIS Systems (OpenELIS, STARLIMS, Medilab)

### Critical Missing Features (Biggest Impact)

#### 1. Result Printing / Report Generation (HIGH PRIORITY)
**What exists:** `lis-result-report.service.ts` has generate/publish/download methods, and `patient-portal` component exists.
**What's missing:** No actual **print template** system — no way to:
- Design result report templates (header, footer, logo, doctor signature)
- Print single patient results or batch print
- Auto-generate PDF with lab letterhead
- QR code on printed reports for verification
- This is the **#1 daily output** of any lab — techs print 100+ reports/day

#### 2. Barcode Label Printing (HIGH PRIORITY)
**What's missing:**
- No barcode label generation for specimen tubes
- After request creation, lab should print labels (barcode + patient name + test + specimen type)
- This is critical for sample identification — every lab does this

#### 3. Machine Interface / HL7 Integration (MEDIUM-HIGH)
**What exists:** Machines CRUD, `machine-results` permissions exist
**What's missing:**
- No HL7/ASTM message handling for analyzer connectivity
- No auto-result import from instruments
- Most modern LIS systems receive results directly from analyzers
- Currently all results are **manually entered** — huge bottleneck for high-volume labs

#### 4. Delta Check / Critical Value Alerts (MEDIUM)
**What exists:** `delta_check_result` and `critical_low/critical_high` fields on results
**What's missing:**
- No automatic comparison with patient's previous results
- No alert notification when critical values detected
- No auto-notification to ordering doctor for critical results
- These are **CAP/CLIA requirements** for accredited labs

#### 5. Worklist Management (MEDIUM)
**What's missing:**
- No daily worklist per section/machine
- No pending test queue prioritized by urgency
- No auto-assignment of tests to technicians
- Top LIS systems generate worklists sorted by: STAT first → Urgent → Routine

#### 6. Sample Rejection Management (LOW-MEDIUM)
**What exists:** Basic reject with reason
**What's missing:**
- No rejection code taxonomy (hemolyzed, clotted, insufficient, wrong tube, etc.)
- No recollection request generation
- No rejection rate analytics

### Design & UX Issues (Current Problems)

#### 1. Results Entry is Slow
**Current:** Select request → expand accordion → enter one result → save → repeat
**Should be:** Spreadsheet-style grid entry — all tests in one view, tab between fields, auto-save on Enter
**Impact:** A tech entering 200+ results/day loses significant time with current accordion UI

#### 2. No Request Search in Kanban/Results
**Current:** Results page filters by date only, kanban by section
**Should have:** Global barcode/request number search that instantly finds any request regardless of date/section

#### 3. No Quick Re-print / Re-send
**Current:** No way to quickly re-print a previous result or re-send to patient
**Should have:** One-click from request list or result view

#### 4. No Patient History View
**Current:** Patient CRUD only, no historical view of all their tests
**Should have:** Click patient → see all requests, results, trend charts for repeated tests (e.g., glucose over 6 months)

#### 5. Dashboard is Read-Only
**Current:** KPI cards showing summary numbers
**Should have:** Clickable cards (click "pending results" → goes to results page filtered), today's urgent tests, action items

#### 6. No Batch Operations on Results Page
**Current:** Enter/validate/approve one result at a time
**Should have:** Select multiple → bulk validate → bulk approve → bulk release

### Financial Workflow Gaps

#### 1. No Split Invoicing Implementation (tickets exist #B3)
**Current:** Single invoice per request
**Should have:** Patient gets invoice for their share, insurance company gets separate invoice for their share
**Status:** Planned in Phase B tickets

#### 2. No Cost Calculation (tickets exist #344-351)
**Current:** No way to know what each test COSTS the lab
**Should have:** Reagent cost + machine cost + labor + overhead per test
**Status:** Design approved, 8 tickets created

#### 3. No Profitability Analysis
**Current:** Revenue reports only
**Should have:** Revenue - Cost = Profit per test, per section, per doctor, per insurance company

#### 4. No Aging Reports
**Current:** No accounts receivable aging
**Should have:** Insurance claims aging (30/60/90 day), patient balance aging

### Workflow Completeness Issues

| Step | Current Status | Gap |
|------|---------------|-----|
| 1. Patient registration | Working | No duplicate detection |
| 2. Request creation | Working | No template/favorite orders |
| 3. Label printing | **MISSING** | Critical gap |
| 4. Sample collection | Working | No phlebotomy queue |
| 5. Sample receiving | Working (kanban) | Good with redesign |
| 6. Processing/analysis | Manual only | No machine interface |
| 7. Result entry | Working but slow | Needs grid UI |
| 8. QC review | Working | No Westgard rule violations |
| 9. Result validation | Working | No auto-validation rules |
| 10. Result approval | Working | No batch approval |
| 11. Result release | Working | No conditional release |
| 12. Report printing | **MISSING** | Critical gap |
| 13. Report delivery | Partial | API exists, no UI |
| 14. Invoicing | Working | No split invoicing |
| 15. Payment | Working | No statement generation |
| 16. Insurance claim | Working | No claim status tracking |

## Priority Recommendations (What to Fix First)

### Tier 1 — Do Now (Most Impact, Users Ask Daily)
1. **Result report printing** — Design template system, PDF generation, batch print
2. **Barcode label printing** — After request → print specimen labels
3. **Results grid entry** — Replace accordion with spreadsheet-style grid
4. **External lab portal** — Login for external labs to enter results

### Tier 2 — Do Soon (Operational Efficiency)
5. **Patient history view** — Click patient → see all results + trends
6. **Batch result operations** — Multi-select validate/approve/release
7. **Cost calculation system** — (Already planned, tickets #344-351)
8. **Split invoicing** — (Already planned, Phase B tickets)

### Tier 3 — Do Later (Competitive Advantage)
9. **Machine/analyzer integration** — HL7/ASTM connectivity
10. **Auto-validation rules** — Skip manual validation for normal results
11. **Critical value alerts** — Auto-notify doctor on critical results
12. **Worklist generation** — Daily work queues per section

### Tier 4 — Nice to Have
13. **Duplicate patient detection** — Merge/link duplicates
14. **Favorite/template orders** — Quick reorder common test panels
15. **SMS/WhatsApp result delivery** — Automated patient notifications
16. **Dashboard drill-down** — Clickable KPIs to filtered views
