Diagnosis of viral upper respiratory tract infections – colds and flu
Based on the symptoms and a physical examination, a doctor can diagnose a cold or flu. In some situations, the tests are carried out, such, as sowing throat culture or blood test. Usually they run in severe condition of the patient and to identify other related problems.
In the definition of the specific types of viruses, causing symptoms are usually not necessary, because the method of treatment is the same regardless of the type of infection. But, if there is suspicion of influenza A virus (based on the time of year and forecasts of doctors), then to detect it can examine the patient specifically.
Diagnosis of colds and flu can include the following:
Thermometer – temperature measurement every 6-8 hours will help determine the severity of the disease.
Analysis of urine – performed in the presence of certain diseases, such as diabetes, which can worsen the symptoms of a cold or flu. Urine is usually performed, if there is a suspicion of urinary tract infections, in the presence of suggestive symptoms or a fever with symptoms of incomplete.
Blood test – standard analysis to evaluate the overall health and ability to resist disease. Test for colds and flu is carried out in cases of serious health problems.
Culture throat – is performed if there are signs or symptoms of angina, to determine the cause of sore throat.
Chest X-ray – If the doctor suspects, that upper respiratory infection has spread to the lungs, X-rays may be done to look for signs of pneumonia.
Screening tests, used for early detection of disease in humans at increased risk are not used for the diagnosis of colds and flu. Diagnosis and treatment begins with the onset of symptoms.
