PNH Flow Cytometry is an advanced diagnostic test used to detect PNH clones in red cells, white cells, and platelets using highly sensitive flow cytometry analysis. It is essential for early diagno
Paroxysmal Nocturnal Hemoglobinuria (PNH) is a rare, life-threatening blood disorder caused by a deficiency of certain protective proteins on blood cells. This makes the cells highly susceptible to destruction by the immune system. PNH Flow Cytometry is considered the gold-standard method for detecting PNH clones because it offers exceptional accuracy, sensitivity, and speed.
Using flow cytometry, FACS analysis, and flow cytometry antibodies, the test identifies GPI-anchored proteins such as CD55 and CD59 on blood cells. Any deficiency or absence of these proteins indicates the presence of PNH clones. This technique is far superior to conventional tests because it can detect even very small clones (<1%), making it crucial for early diagnosis and treatment.
PNH can cause severe complications including chronic hemolysis, blood clots, kidney damage, and life-threatening infections. Early identification of clone size and monitoring over time is essential for managing these risks.
The PNH Flow Cytometry Test is important for several reasons:
Gold-standard diagnostic tool for PNH detection
High-sensitivity detection with flow cytometry analysis
Identifies deficiency of CD55, CD59, and other GPI-linked markers
Helps differentiate PNH from other hemolytic anemias
Essential in evaluating patients with aplastic anemia, myelodysplastic syndromes, or unexplained hemolysis
Supports treatment decisions and response monitoring for drugs like eculizumab and ravulizumab
Because PNH may progress silently, regular monitoring through flow cytometry ensures timely medical intervention.
The testing procedure is simple, minimally invasive, and highly accurate. Flow cytometry allows thousands of cells to be analyzed within seconds using fluorescent markers and FACS cytometry technology.
Sample Collection: A small blood sample is collected in an EDTA tube.
Lab Processing: The sample is stained with specific flow cytometry antibodies targeting CD55, CD59, and other GPI-anchored proteins.
Flow Cytometry Analysis: Using FACS flow cytometry, the instrument passes laser light through each cell, evaluating the presence or absence of protective proteins.
Interpretation: The percentage of PNH clones in RBCs, neutrophils, and monocytes is calculated.
Reporting: Clone size, pattern, and clinical correlation are provided.

Diagnopein ensures accurate detection and monitoring, supporting better clinical outcomes for patients with PNH and related disorders.
The test is low-risk, primarily involving a blood draw. Potential risks include minor discomfort, bruising, or infection at the puncture site.
A blood sample is drawn from the patient, and flow cytometry is used to analyze the red blood cells for the absence of GPI-anchored proteins (e.g., CD55 and CD59), which indicates PNH.
The test is performed to diagnose PNH, especially in patients exhibiting symptoms such as dark-colored urine, fatigue, and unexplained anemia. It helps differentiate PNH from other hematological disorders.
While the PNH test is critical for diagnosis, it may be used alongside other tests, such as complete blood counts and hemoglobin electrophoresis, to provide a comprehensive evaluation.
