A Gram stain is a laboratory test that checks for bacteria at the site of a suspected infection or in certain bodily fluids. A medical laboratory scientist processes the Gram stain, which gives relatively quick results, so healthcare providers can know if bacteria are present, and, if so, the general type(s). This can help guide further identificat...
If bacteria are present on a Gram stain slide, a medical laboratory scientist classifies them as gram-negative or gram-positive based on which color they turn under a series of stains. There are also gram-variable bacteria, which means they stain irregularly, and there’s a mix of pink- and purple-colored bacteria. It’s important to note that gram-n...
Healthcare providers use both Gram stains and bacteria cultures if they suspect you have a bacterial infection. However, these tests provide different information. Providers usually request bacteria culture tests alongside Gram stain tests. In a bacteria culture test, a medical laboratory scientist takes cells from the sample that’s also for the Gr...
Healthcare providers order Gram stains to help diagnose and treat certain bacterial infections, such as urinary tract infections (UTIs) and bacterial pneumonia. Providers may not always request a Gram stain to help diagnose conditions caused by bacteria. For example, they usually don’t Gram stain for food poisoning, but it’s possible to do so throu...
Healthcare providers typically request a Gram stain along with a bacteria culture when they suspect you have a bacterial, or sometimes fungal, infection. It’s one of the most common ways to quickly diagnose bacterial infection in your body.
Depending on what kind of infection you may have, many types of healthcare providers could collect a sample for a Gram stain test. For example, a gynecologist may collect a swab for a gonorrhea Gram stain test and a pulmonologist may collect a sample of your spit or mucus from your cough to use for a bacterial pneumonia Gram stain test. Your provid...
May 8, 2021 · Serological and immunological tests are primarily applied for population-based seroprevalence studies to evaluate the effectiveness of COVID-19 control measures and increase our understanding of the immunology behind COVID-19. Combining molecular diagnostics with serological tests may optimize the detection of COVID-19.
