PENNSYLVANIA (WJAC) — As Measles cases continue to rise across Pennsylvania, concerns are also growing within the medical profession, with the state’s Department of Health now promoting something called a ‘Titer Test.’

Officials explain that it is a simple blood test to determine if someone has the measles antibodies in their bloodstream.

Johnstown area doctor Richard Wozniak trains doctors in Conemaugh’s residency program and says that one of the best things someone can do to prevent the infection is to get vaccinated.

The measles vaccine was developed in 1967, and doctors say that for those who have had their routine childhood vaccinations since then, they should be immune.

But for those who are unsure, doctors say it’s best to get the test done.

Medical officials say the test measures the level of antibodies in one’s bloodstream to determine if they are healthy enough to fight off a potential measles infection.

Officials say the test is available to all ages, and regardless of any preexisting health conditions.

Doctor Wozniak notes that measles is so contagious that 90-percent of those without immunity will catch it after coming in contact with an infected person.
