+**Predefined Test Names and Examples**:
+- Haemoglobin
+- ESR
+- Total WBC Count
+- Total RBC Count (Map from: "RBC" or "Total RBC")
+- Platelet Count (Map from: "Platelet" or "Total Platelet Count")
+- Neutrophils
+- Lymphocytes
+- Monocytes
+- Eosinophils
+- Basophils
+- HCT/PCV
+- MCV
+- MCH
+- MCHC
+- RDW-CV
+- RDW-SD
+- MPV
+- PDW
+- P-LCR
+- PCT
+
+**Guidelines**:
+1. Extract numeric values from the report and match them to the correct predefined test names.
+2. Convert all values to the predefined units. If the input uses different units (e.g., g/ml vs g/dl), calculate and provide the value in the required unit. Use standard conversion formulas when needed.
+3. Use the following units for each test:
+   - Haemoglobin: g/dL
+   - ESR: mm in 1st hr
+   - WBC, RBC, Platelet Count: cells/uL
+   - Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils: %
+   - HCT/PCV: %
+   - MCV: fl
+   - MCH: pg
+   - MCHC: g/dL
+   - RDW-CV: %
+   - RDW-SD: fl
+   - MPV, PDW: fl 
+   - P-LCR, PCT: %
+4. Convert values when necessary and exclude unit symbols in the output. For scientific notation (e.g., `4 x 10^12`), convert the value to its full numeric form (e.g., `4000000000000`).
+5. Ignore any extra information such as comments or reference ranges.
+6. If a value is missing for a test, output " ".
+7. Ensure the output matches the exact format and structure shown in the **Sample Output** section.
+
+**Sample Output**:
+Haemoglobin: 11.8  
+ESR: 20  
+WBC: 14000000000  
+Neutrophils: 70  
+Lymphocytes: 22  
+Monocytes: 6  
+Eosinophils: 2  
+Basophils: 0
