The flu is a contagious respiratory health problem. It is caused by the influenza virus. Symptoms of flu can be mild to severe. In severe cases, it may lead to the death of the affected individual. At ER of Dallas, we conduct all kinds of flu diagnostic tests. The results can range from negative and slightly positive flu tests.
A false-positive flu test takes place when the flu or influenza season is concluding. Similarly, false-negative flu tests take place when the flu season is at its peak. And the chances of people suffering from the disease are high.
