Laboratory diagnosis is a crucial aspect of identifying and treating infectious diseases. Laboratory tests can identify organisms directly (e.g., visually, using a microscope, growing the organism in culture) or indirectly (e.g., identifying antibodies to the organism). General types of tests include microscopy, culture, immunologic tests (such as latex agglutination, enzyme immunoassays, Western blot, precipitation tests, and complement fixation tests), nucleic acid-based identification methods, and non-nucleic acid-based identification methods. Culture is normally the gold standard for identification of organisms, but results may not be available for days or weeks, and not all pathogens can be cultured, making alternative tests useful.

    Pneumococcal pneumonia is caused by the bacterium Streptococcus pneumoniae. Laboratory diagnosis of pneumococcal pneumonia can be done through several methods, including blood tests, chest X-rays, pulse oximetry, sputum test, and urine test. Blood tests can confirm an infection and try to identify the type of organism causing the infection. A chest X-ray can help diagnose pneumonia and determine the extent and location of the infection. Pulse oximetry measures the oxygen level in your blood. A sputum test can confirm the cause of infection. A urine test can identify bacterial infection of Streptococcus pneumoniae.

    Laboratory diagnosis of Streptococcus pyogenes can be done using several methods, including microscopy, culture, rapid antigen test, and molecular tests such as polymerase chain reaction (PCR). Specimens for bacteriological investigations can include pus or exudate. Gram staining of pus or exudate is a rapid and presumptive diagnostic procedure. A throat swab culture is the most specific method for diagnosis. A swab sample from your throat can be tested for the presence of S. pyogenes using a rapid antigen test or PCR test. Is

    Medical laboratory diagnosis:
    The primary objective in laboratory diagnosis is to identify whether the diagnosed S. aureus isolate is methicillin-resistant. Since MRSA emerged as a problematic pathogen, a systematic diagnostic approach is necessary for early diagnosis so that treatment with appropriate antibiotics can be initiated as early as possible. For species identification, slide and tube coagulase tests, latex agglutination tests, and PCR-based tests are used. For detection of MRSA, determination of minimum inhibitory concentration (MIC) of methicillin or oxacillin or cefoxitin using broth micro-dilution method, cefoxitin disk screen, oxacillin agar screen and latex agglutination test for PBP2a and molecular methods for detection of mecA are employed.

    Malaria parasites can be identified by examining under the microscope a drop of the patient’s blood, spread out as a “blood smear” on a microscope slide. Prior to the examination, the specimen is stained (most often with the Giemsa stain) to give the parasites a distinctive appearance. This technique remains the gold standard for laboratory confirmation of malaria. However, it depends on the quality of the reagents, of the microscope, and on the experience of the laboratorian

    UTIs can be diagnosed by analyzing a patient’s urine sample. The two most common tests to detect UTIs are a urinalysis and a urine culture with antimicrobial susceptibility testing:

    1. Urinalysis: A urinalysis is a group of physical, chemical, and microscopic tests on a sample of urine. These tests look for evidence of infection, such as bacteria and white blood cells.

    2. Urine culture: This is a test that detects and identifies specific bacteria and yeast in a patient’s urine that may be causing a UTI. Urine cultures can also help doctors determine the best antibiotic for treating a UTI.

    3. Susceptibility testing: Susceptibility testing measures how sensitive the bacteria is to an antibiotic or antifungal drug. This helps doctors determine which treatment is most appropriate.
