Infection & Immunity Testing
Infection and immunity testing helps healthcare professionals investigate possible infections and assess specific immune responses through appropriate laboratory tests. These tests can be recommended when symptoms, medical history, exposure, or other clinical findings suggest the need for further evaluation.
What Does Infection Testing Include?
The tests selected depend on the suspected infection and the patient's individual circumstances. Infection blood tests may look for antibodies, antigens, or other markers associated with specific infections. Depending on the condition being investigated, testing may also involve blood, urine, swab, or other clinical samples.
When Is Testing Recommended?
A healthcare professional may recommend infection testing when a person has symptoms such as fever, unexplained fatigue, persistent inflammation, swollen lymph nodes, or other signs that could be associated with an infection. Testing may also be advised after certain exposures or as part of monitoring an existing condition.
Understanding Immunity Testing
Immunity tests can assess whether specific antibodies are present in the blood. The meaning of an antibody result depends on the particular test, timing, vaccination history, previous infection, and clinical circumstances. Not every antibody result indicates active infection.
Why Accurate Testing Matters
Laboratory testing provides valuable information that can help healthcare professionals determine whether additional evaluation or treatment is appropriate. Test selection and interpretation should always be based on the individual's symptoms, medical history, and suspected condition.
Preparing for Your Test
Preparation requirements vary depending on the investigation. Follow the instructions provided before sample collection and inform your healthcare professional about relevant medications, vaccinations, recent illnesses, and medical history.
