Test Overview & Methodology
The Leucocyte Alkaline Phosphatase (LAP) Score is a specialized cytochemical stain that quantifies enzyme activity within neutrophils, providing critical distinction between chronic myeloid leukaemia (low score) and benign leukemoid reactions (high score). DNA Labs UAE utilizes digital cytochemistry with reflex LC‑MS/MS confirmation for robust diagnostic accuracy.
| Feature | DNA Labs UAE LAP Score | Alternative (Bone Marrow Biopsy) |
|---|---|---|
| Diagnostic Focus | Neutrophil enzyme activity; differentiates CML vs. reactive leukocytosis | Marrow morphology and fibrosis; broader but invasive |
| Methodology | Digital cytochemistry with reflex LC‑MS/MS | Histopathology / IHC |
| Turnaround Time | 7 days | 2–3 weeks |
| Invasiveness | Minimal – finger prick blood smear | High – needle aspiration from iliac crest |
Physician Insight & Safety Protocols
Mr. Prabhakar Reddy Kalathoor, Specialist Diagnostic Radiology (DHA 61713011): "From a diagnostic imaging perspective, the LAP Score provides critical corroborative data when evaluating suspected myeloproliferative disorders. A low score in the setting of splenomegaly or marrow signal changes on MRI strengthens the suspicion for chronic myeloid leukemia. No single laboratory parameter should be interpreted without full clinical and radiological context."
Medication Advisory
Important Safety Alert
Do not discontinue prescribed medication without consulting your doctor. The LAP Score does not replace ongoing clinical monitoring.
Safety Exclusion Criteria & ER Red Flags
Exclusion and Emergency Guidance
- Exclusion Criteria: Active febrile illness, known bleeding diathesis, or current anticoagulant therapy without physician clearance may invalidate results or pose collection risks.
- ER Red Flags: Sudden severe bleeding from the finger puncture, fainting, or signs of systemic infection (fever, chills) after collection – seek emergency medical attention immediately.
- Minors: In compliance with Federal Decree-Law No. 4 of 2016 on Medical Liability, individuals under 18 require documented guardian consent and must be accompanied during sample collection.
Patient FAQ & Clinical Guidance
1. What is the LAP Score test?
The LAP Score test quantifies alkaline phosphatase enzyme activity in neutrophils to distinguish malignant from benign leukocytosis. This cytochemical staining provides a semi‑quantitative score that, alongside clinical and molecular markers, helps differentiate chronic myeloid leukemia (typically low score) from leukemoid reactions or myeloproliferative neoplasms with elevated scores.
2. How is the LAP Score sample collected?
A certified phlebotomist performs a simple finger prick to obtain capillary blood, prepares five smears, and fixes them in ethanol; the entire procedure takes under 10 minutes. No fasting or special preparation is required, making it ideal for in‑clinic or ISO‑certified home collection.
3. When will I receive my LAP Score results?
Your LAP Score results are typically ready within one week, and our specialist provides a telephonic interpretation upon request. Urgent preliminary reporting is available for clinically emergent cases; our WhatsApp support team will coordinate expedited delivery once the smear analysis is complete.
4. Can the LAP Score test be performed at home?
Yes, DNA Labs UAE offers VIP Mobile Phlebotomy with temperature‑controlled cold‑chain transport for home collection daily from 8 AM to 11 PM. The finger‑prick method is minimally invasive and safe for most patients.
