A Gram stain is used, along with a culture of the material from an infected site, to identify the cause of a bacterial infection. The Gram stain provides preliminary results on whether bacteria are present and the general type, such as the shape and whether they are Gram-positive or Gram-negative.Often, detecting the presence of bacteria and determining whether an infection is caused by a microbe that is Gram-positive or Gram-negative will be sufficient to allow a healthcare practitioner to prescribe treatment with an appropriate antibiotic while waiting for more specific tests, such as a culture, to be completed. Absence or presence of white blood cells in the Gram stain can help establish that an adequate sample was obtained as white blood cells are frequently present with an infection.A Gram stain may also be performed as part of the evaluation of a culture. When bacteria grow on/in a nutrient media in the laboratory, a Gram stain is performed to help determine the type of bacteria present and to help determine what other tests may need to be performed to definitively identify the cause of infection.Fungi, including yeast, may also be detected with a Gram stain.
