Doctors can determine if an infection is occurring through a combination of physical examination, medical history, and diagnostic tests. Some common signs and symptoms of infection include fever, chills, fatigue, pain, redness, swelling, and warmth at the site of infection.
Doctors may also order laboratory tests such as blood tests, urine tests, or cultures to identify the specific type of infection-causing organism. Imaging tests such as X-rays, CT scans, or MRIs may also be used to visualize the infection and assess its severity.
In some cases, doctors may perform a biopsy, where a small sample of tissue is taken from the infected area and examined under a microscope to determine the presence of infection. Overall, a combination of clinical assessment and diagnostic tests is used to confirm the presence of an infection and determine the appropriate treatment.

Doctors use several methods to determine if an infection is occurring:
Clinical Examination:
- Physical examination to check for signs of infection, such as redness, swelling, pus, or tenderness.
- Checking vital signs, such as temperature, pulse, and respiratory rate, which may be elevated in the presence of infection.
Medical History:
- Asking the patient about symptoms, such as fever, chills, pain, or discharge.
- Reviewing the patient's medical history, including recent surgeries, wounds, or contact with infectious individuals.
Laboratory Tests:
- Blood tests:
- White blood cell count (WBC): Elevated levels may indicate an infection.
- Differential count: Specific types of white blood cells increase to fight different infections.
- Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP): These can indicate inflammation, a sign of infection.
- Urine tests:
- Urinalysis: Microscopic examination of the urine can reveal signs of infection, such as white blood cells or bacteria.
- Culture and sensitivity tests:
- A sample of blood, urine, or other fluid is collected and cultured to grow any bacteria or fungi present.
- The culture is then tested to determine the specific organism causing the infection and its sensitivity to antibiotics.
Imaging Tests:
- X-rays: Can reveal signs of infection in the lungs or bones.
- Ultrasound: Can visualize abscesses or fluid collections that may indicate an infection.
- Computed tomography (CT) scans: Can provide detailed images of internal organs and identify signs of infection.
Additional Methods:
- Swabs or scrapings: Collecting samples from wounds or lesions to examine under a microscope or culture.
- Endoscopy: Inserting a thin, flexible tube with a camera to visualize internal organs and check for signs of infection.
- Biopsy: Removing a sample of tissue for examination under a microscope to diagnose an infection.
