TDap Titer Blood Test Panel
The TDap Titer Blood Test Panel detects antibodies and helps determine if an individual has been vaccinated against or previously infected by tetanus, diphtheria, and pertussis.
What is a "titer"?
The term titer refers to the number of antibodies (a blood protein) detected within an individual's blood. The amount and range of antibodies directly correlate to the strength of the body's immune system. Therefore, titer tests are conducted to determine the immunity level to a particular disease.
What is the purpose of this test?
Order this TDap Titer Blood Test Panel to detect antibodies and help determine if an individual has been vaccinated against or previously infected by diseases such as tetanus, diphtheria, and pertussis.
Tetanus, also known as "lockjaw," is an infection caused by Clostridium tetani bacteria. Clostridium tetani spores can be found everywhere in the environment, including soil, dust, and manure. Once these bacteria enter the body, they produce a toxin that causes painful muscle spasms leading an individual's neck and jaw muscles to lock. These muscle spasms can also spread to other parts of the body.
Diphtheria is an infection caused by strains of Corynebacterium diphtheriae, which usually affects the nose and throat. Diphtheria is contagious and spreads through respiratory droplets, like coughing or sneezing. In addition, individuals can contract this disease by touching infected open sores or ulcers.
Pertussis, or "whooping cough," is a respiratory infection that causes uncontrollable coughing. This infection is caused by a type of bacteria called Bordetella pertussis. The name of the disease comes from the whooping noise individuals might make when they try to breathe in after coughing. Whooping cough is contagious and can affect all ages, but it can be especially severe in babies not yet vaccinated. Nearly half of the babies under age one infected with whooping cough need care in the hospital.
When should I order a TDap Titer Blood Test Panel?
Often certain companies or institutions require their workers or students to provide proof of immunizations. This blood titer test can determine if an individual has antibodies to a disease because they've received a vaccination or already have the disease and are no longer susceptible. If not, individuals will generally need a vaccine or a booster. Individuals are advised to contact their healthcare provider for further questions regarding immunity.
