Final answer:
Inflammation has clinical signs such as redness, swelling, warmth, pain, and loss of function. It can last for a short period (acute) or become chronic. Screening for unseeable inflammation can be done using lab tests like CRP and ESR, as well as imaging techniques like MRI and ultrasound.
Step-by-step explanation:
The clinical appearance of inflammation includes redness, swelling, warmth, pain, and sometimes a loss of function. These signs and symptoms are caused by increased blood flow and various processes in the infected tissue. Inflammation can be acute, lasting for a short period and localized to the site of injury or infection, or it can be chronic, resulting in the formation of granulomas and scarring.
To screen for unseeable inflammation, doctors may order lab tests such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). These tests measure certain markers in the blood that indicate the presence of inflammation. Imaging techniques like MRI and ultrasound can also be used to detect inflammation in specific organs or tissues.
