What diseases can be detected through blood culture?

Generally, blood culture tests may detect diseases such as sepsis, osteomyelitis, bacterial pneumonia, infective endocarditis, and fungal bloodstream infections. If experiencing any discomfort, it is recommended to seek medical attention immediately and receive symptomatic treatment under the guidance of a qualified physician. Detailed explanations are as follows:

1. Sepsis

Sepsis refers to an acute systemic infection caused by pathogenic microorganisms entering the bloodstream and producing toxins. Patients may experience symptoms such as high fever, chills, and rash. Blood cultures can directly detect the causative pathogens, such as bacteria and fungi.

2. Osteomyelitis

Osteomyelitis is an inflammatory condition caused by bacterial infection of the bone marrow cavity, periosteum, and trabeculae of the bone. Patients may experience localized pain, swelling, and other symptoms. Blood cultures aid in identifying the causative pathogen in diagnosing osteomyelitis and provide information for treatment planning.

3. Bacterial Pneumonia

Bacterial pneumonia is an inflammatory condition of the lungs caused by bacterial infection. Patients may experience symptoms such as cough, sputum production, and fever. Blood cultures can detect the bacteria causing pneumonia, such as Streptococcus pneumoniae and Staphylococcus aureus, thus guiding antibiotic therapy.

4. Infective Endocarditis

Infective endocarditis refers to a disease caused by microbial infection of the heart valves or endocardium of the ventricular wall, resulting in an inflammatory response. Patients may exhibit symptoms such as fever, heart murmurs, and anemia. Blood cultures can help physicians identify the causative pathogen of endocarditis and select an appropriate treatment plan.

5. Fungal Bloodstream Infection (Fungemia)

Fungal bloodstream infection refers to a condition caused by fungi entering the bloodstream. Patients may experience symptoms such as fever, chills, and rash. Blood cultures can directly detect fungal pathogens, thereby guiding antifungal treatment.

Maintaining good hygiene practices, avoiding contact with sources of infection, and engaging in regular physical exercise can help improve the body's immune system.
