Phenol red is another indicator commonly used to detect the presence of acid. This indicator is red above pH7 and yellow below pH of 7. What would be the appearance of E. coli (gram negative rod, lactose fermenter) and S. aureus (gram positive cocci, lactose fermenter) if neutral red in MacConkey agar was replaced with phenol red?

4. What are four test systems that employ low reagent phospholipid concentrations to detect LA as a result of it prolonging the clot formation time? 5. Which two of these tests are used in combination by most specialty or reference laboratories in the United States to detect or help rule out LAs? 6. Why do LAs prolong phospholipid-dependent clot formation? 7. What is the effect upon clotting time of adding excess phospholipids and repeating a true- positive LA screening test?...

29.) An immunoassay was performed in the following way: Antigen is bound to a solid support. Patient serum is added and patient antibodies bind to the antigen. The well is washed and enzyme-labeled anti-immunoglobulin antibodies are added. The well is washed and enzyme substrate is added and enzyme activity is determined. Which immunoassay is described? A. latex agglutination B. competitive C. ELISA D. homogeneous 30.) Erythema migrans (EM) is the caused by tick bite: A. itchy rash B. red bull's-eye...

HDN= Hemolytic disease of the newborn
2. What test would you perform in order to identify the antibody causing the HDN? 3. A new tech is investigating a suspected HDN case but the mother's cells keep on reacting as DAT negative. Assuming that HDN is actually occurring, what is the most likely error being made by the tech? 4. How would you change your titration testing procedure if you thought the antibody causing HDN was an IgG antibody against ABO?...
Diffraction can be used to provide a quick test of the size of red blood cells....
Diffraction can be used to provide a quick test of the size of red blood cells. Blood is smeared onto a slide, and a laser shines through the slide. The size of the cells is very consistent, so the multiple diffraction patterns overlap and produce an overall pattern that is similar to what a single cell would produce. Ideally, the diameter of a red blood cell should be between 7.5 and 8.0 μm. If a 633 nm laser shines through...
