The amount of sputum needed for culture is usually determined based on the doctor's recommendations and laboratory requirements. Typically, 2–5 mL of sputum is required. When collecting a sputum sample, it should be as clear and uncontaminated as possible. It is generally recommended that patients collect their sputum sample upon waking in the morning. Before collection, oral hygiene and hand cleanliness should be ensured. Sputum can be collected through methods such as throat stimulation, deep breathing, and coughing. Patients should first take several deep breaths, then forcefully cough up sputum into the collection container. The collected sample should be sent to the laboratory promptly for culture. Depending on the suspected type of infection, the required sputum volume may vary: approximately 2 mL is needed when a common bacterial infection is suspected, while 3–5 mL is required for suspected fungal or parasitic infections.
In summary, typically 2–5 mL of sputum is required. However, since requirements may vary between hospitals and depending on the suspected condition, the exact volume may differ. It is recommended to visit a正规 hospital and follow medical staff instructions for proper sample collection.
