Pus is a thick fluid composed of dead white blood cells, bacteria, and tissue debris, usually collected from abscesses, wounds, or infected sites.

The sample is cultured to isolate bacteria or fungi responsible for infection.

Once organisms are identified, antibiotic sensitivity testing is performed to determine effective treatment options.

Clinical uses include:

Diagnosing skin and soft tissue infections.

Identifying causative organisms in abscesses, boils, or post‑surgical infections.

Guiding antibiotic therapy to avoid resistance.

Monitoring recurrent or complicated infections.

Provides definitive microbiological evidence for infection management.

Analyte: Microorganisms present in pus samples.

Normal Result: No growth (sterile sample).

Abnormal Findings:

Positive culture: Indicates presence of pathogenic organisms (e.g., Staphylococcus aureus, Streptococcus, Klebsiella, Pseudomonas, Candida).

Sensitivity profile: Identifies antibiotics effective against the isolated organism.

Clinical Use:

Provides a direct microbiological diagnosis of pus‑forming infections.

Helps guide precise antimicrobial therapy.

Supports surgery, dermatology, infectious disease, and general medicine evaluations.
