Measles, also known as rubeola, is responsible for the deaths of about one million children each year. The Measles – PCR – Qualitative test helps to diagnose it.
What is Measles – PCR – Qualitative?
Measles – PCR – Qualitative is a diagnostic test that makes use of real-time polymerase chain reaction (PCR) to detect the measles infection in a serum sample/respiratory specimen .
Measles is a highly virulent illness caused by the single-stranded enveloped RNA virus. Humans are the only natural hosts for this virus, and the disease can be passed on to unborn children. Measles – PCR – Qualitative helps to isolate the nucleic acid associated with the RNA virus and thus detect measles early.
Measles – PCR – Qualitative is a simple, fast and accurate procedure and is hence a preferred technique.
Why is Measles – PCR – Qualitative suggested?
Measles – PCR – Qualitative is suggested in the following cases:
- To confirm the presence of measles in a patient with symptoms.
- To confirm immunity after vaccination.
How is Measles – PCR – Qualitative performed?
Measles – PCR – Qualitative is performed by a trained pathologist.
- A blood sample is collected from the patient.
- Centrifugal tubes are used to separate the serum.
- Samples should be stored at 4 degrees Celsius and transported on wet ice packs .
A throat swab is also usually taken for Measles – PCR – Qualitative.
Parameters measured in Measles – PCR – Qualitative
The following parameters are relevant in Measles – PCR – Qualitative
- Detection of the nucleic acid specific to measles .
- Presence of febrile rash in the patient.
Preparations before performing Measles – PCR – Qualitative
The following preparations will help ensure that Measles – PCR – Qualitative goes smoothly.
- Women should inform their pathologist of pregnancies as measles can be transmitted to the child.
- Patients should inform pathologists of all medications being taken.
Post-care after Measles – PCR – Qualitative
No specific post-care is needed after Measles – PCR – Qualitative.
Sample types with Measles – PCR – Qualitative
The following samples are usually needed for Measles – PCR – Qualitative.
- Throat swab.
- Serum sample.
- Urine sample.
Side effects/risks of Measles – PCR – Qualitative
The following risks are associated with Measles – PCR – Qualitative.
- Mild risk of excessive bleeding when taking blood sample.
