What Is a TB Skin Test?
A TB skin test (Mantoux test) is used to determine whether a person has been exposed to tuberculosis bacteria. This is an easy process where a small amount of testing solution is injected just under the skin.
The injection is typically performed in the arm. The result is examined after about 48 to 72 hours.
Healthcare Workers and Medical Staff
Individuals employed within the health sector come into frequent contact with patients and have a greater chance of exposure to TB.
Regular screening for TB infection is recommended for employees working within hospitals, clinics, and care centers.
People Who Have Been Exposed to TB
Individuals who were in close contact with people suffering from active TB infections need to be tested.
These include individuals such as family members, colleagues, or anyone who spent considerable time with the affected individual.
Individuals with Weakened Immune Systems
A person with a weakened immune system is highly likely to contract the disease when exposed.
This can be found among individuals suffering from HIV infection, undergoing chemotherapy, or taking immunosuppressive drugs.
People Traveling to or from High-Risk Areas
There are some countries where there is a high prevalence rate of TB infections, thereby putting an individual at risk of getting the disease.
People visiting such countries should undergo testing irrespective of whether they show any symptoms or not.
Individuals in Group Living Environments
Tuberculosis is known to spread easily due to close contact. This can happen through shelters, jails, nursing homes, and other places where people live together.
People with TB Symptoms
If you experience symptoms of tuberculosis, your healthcare provider may recommend further evaluation and testing.
These symptoms may include an ongoing cough, unexpected weight loss, night sweats, fever, and exhaustion.
Why TB Testing Matters
TB can lie dormant in the body for an extended period of time without causing any symptoms. Testing can help identify a latent TB infection early on, allowing for proper treatment and preventing the spread of the disease.
