Measles – PCR – Qualitative

Overview Brief

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 [1].

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 [2].

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 [3].
  • 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.
