Bacterial skin infections are diagnosed through clinical evaluation and laboratory tests. Doctors usually examine the affected area for redness, swelling, pus, and other signs of infection. In some cases, a sample of tissue or fluid may be taken for culture to identify the specific bacteria responsible. Blood tests might be done if the infection is severe or spreading. Common bacterial infections include cellulitis, impetigo, and folliculitis. Accurate diagnosis ensures the right antibiotic treatment, such as cephalexin capsules, which are widely distributed by reputable cephalexin capsules distributors to treat various bacterial skin infections effectively and prevent complications.
