Which of the following laboratory tests would be best to confirm PNH?

Which of the following laboratory tests would be best to confirm PNH?

Flow cytometry is the preferred technique for the diagnosis of PNH and is performed to evaluate for the presence of GPI-linked antigens on blood cells.

Which test can confirm a paroxysmal nocturnal hemoglobinuria diagnosis in a patient?

The main diagnostic test for individuals with suspected PNH is flow cytometry, a blood test that can identify PNH cells (blood cells that are missing GPI-anchored proteins).

What is the treatment of choice for PNH?

Medical Therapy The mainstay of PNH treatment is the drug eculizumab (Soliris). It is a humanized monoclonal antibody that binds to proteins in the blood that can destroy red blood cells. The drug reduces the risk of thrombosis and can improve quality of life in PNH patients.

What is a PNH screen?

PNH screening is performed by multi-colour flow cytometry which provides a sensitive and reliable recognition of PNH clones by analysis of red cells, neutrophils and monocytes.

When do you treat PNH?

Thrombosis, severe anemia, or PNH symptoms (chronic fatigue, pain, dyspnea) are strong indications for initiating therapy. Terminal complement inhibition increases the risk for Neisseria infection; thus, all patients should be vaccinated against Neisseria.

Why would a doctor order a flow cytometry?

Flow cytometry can identify the type of cells in a blood or bone marrow sample, including the types of cancer cells. It detects types of cancer cells based on either the presence or the absence of certain protein markers (antigens) on a cell’s surface.

Can a bone marrow transplant cure PNH?

Bone marrow transplantation is the only curative therapy for paroxysmal nocturnal hemoglobinuria and has been shown to eradicate the PNH clone in patients with classical paroxysmal nocturnal hemoglobinuria and AA/PNH; however, it is associated with significant morbidity and mortality.
