A Sputum Routine test is a diagnostic test that examines a sample of mucus coughed up from the lungs (sputum) for signs of infection or other abnormal conditions.

Pre-test preparation for a Sputum Routine test typically involves collecting a sputum sample by coughing it up into a container. It is important to collect three consecutive samples in the morning before taking any medication, and to follow the instructions provided by a healthcare professional.

The testing method for a Sputum Routine test typically involves taking a sample of the patient’s sputum and examining it under a microscope for signs of infection, such as bacteria or fungus, or abnormal cells, such as cancer cells. The sample can also be cultured to identify any microorganisms present and to determine their susceptibility to antibiotics.

Common symptoms that may prompt a healthcare provider to prescribe a Sputum Routine test include a persistent cough, chest pain, or difficulty breathing. Other symptoms may include fever, night sweats, or weight loss.

A positive test result from a Sputum Routine test can indicate the presence of infection, such as pneumonia or tuberculosis, or other abnormal conditions, such as lung cancer. However, it’s important to note that other factors such as smoking or exposure to pollution can also cause abnormal results.

The reference range for a Sputum Routine test is typically negative for infection or abnormal cells. However, it’s important to note that the test results can vary based on the lab and the specific test used.

A normal value for a Sputum Routine test is considered to be negative for infection or abnormal cells. However, it’s important to note that a negative test result does not guarantee the absence of disease and other tests such as chest x-ray may be needed to confirm the diagnosis.
It’s also important to consult with a healthcare professional to interpret test results and to understand how they may be affected by individual factors such as medical history, symptoms, and other lab test results.
