Fit Testing | Personal Protective Equipment | CDC The test is a pass fail test that determines whether you can detect a test agent, such as through taste, smell, or an involuntary cough The OSHA-accepted fit test protocols provide complete instructions for conducting qualitative fit tests with the accepted test agents NIOSH does not endorse or recommend the use of the irritant smoke fit test
Testing for COVID-19 | COVID-19 | CDC - Centers for Disease Control and . . . A single NAAT test can be used to confirm an antigen test result *Self-tests, or at-home tests, are antigen tests that can be taken anywhere without having to go to a specific testing site Read self-test package inserts thoroughly and follow the instructions closely when performing the test When you get tested
Overview of Testing for SARS-CoV-2 | COVID-19 | CDC Positive viral test results indicate current infection and the person with COVID-19 should take steps to prevent spreading COVID-19 to others Negative viral test results mean the test did not detect the virus, but this doesn't rule out that the person could have an infection These results represent a snapshot of the time around specimen
Laboratory Testing for CMV and Congenital CMV The enzyme-linked immunosorbent assay (ELISA) is the most common serologic test for measuring antibody to CMV Tests for congenital CMV in newborns Polymerase chain reaction (PCR) on saliva is the standard laboratory test for diagnosing congenital CMV infection Urine is usually collected and tested for confirmation
Information for Diagnostic Laboratories | Rabies | CDC This innovative test targets a highly conserved region of the virus genome including the leader region and nucleoprotein gene, which ensures robust detection across all viruses that can cause rabies The LN34 test works by a single-tube reaction where viral genetic material is amplified into many copies and detected by a fluorescent probe
Clinical Testing and Diagnosis for Tuberculosis - CDC It is the only kind of TB skin test solution that is FDA-approved for this test method After 48–72 hours, the skin test reaction must be examined by a trained health care worker The health care worker measures any swelling where the tuberculin was injected to determine if the reaction to the test is positive or negative
Laboratory Testing for Epstein-Barr Virus (EBV) Monospot test The Monospot test is not recommended for general use The antibodies detected by Monospot can be caused by conditions other than infectious mononucleosis Moreover, studies have shown that the Monospot produces both false positive and false negative results
Clinical Testing and Diagnosis for Lyme Disease - CDC For more information, see: Updated CDC Recommendation for Serologic Diagnosis of Lyme Disease and APHL Guidance and Interpretation of Lyme Disease Serologic Test Results Key points to remember Most Lyme disease tests are serologic assays designed to detect antibodies that can take several weeks to develop following infection; patients may test
Laboratory Testing for Pertussis | Whooping Cough | CDC CDC serologic test CDC and the Food and Drug Administration developed a serologic assay that has been useful for confirming diagnosis, especially during suspected pertussis outbreaks A few state public health laboratories have included this assay as part of their testing regimen for pertussis
Screening for Cervical Cancer | Cervical Cancer | CDC The HPV test and the Pap test can help prevent cervical cancer or find it early The HPV test looks for the virus (human papillomavirus) that can cause cell changes on the cervix The Pap test (or Pap smear) looks for precancers, cell changes on the cervix that might become cervical cancer if they are not treated appropriately
