Nephelometry is based on the principle of: - ️️Turbidity resulting from specific antigen-coated latex particles agglutinated by corresponding antibody Which of the following can cause hemolysis and perhaps result in recollection of the specimen? - ️️Pushing the plunger of a syringe when transferring blood into vacuum tubes. A manual white blood cell count was performed by the hematology technologist. The cell counts for both sides were 99 and 164, respectively. All nine large squar...

B; The correct answer for this question is 1300 mg/dL. The laboratorian performed a 1:4 dilution by adding 0.25 mL (or 250 microliters) of patient sample to 750 microliters of diluent. This creates a total volume of 1000 microliters. So, the patient sample is 250 microliters of the 1000 microliter mixed sample, or a ratio of 1:4. Therefore, the result given by the chemistry analyzer must be multiplied by a dilution factor of 4. 325 mg/dL x 4 = 1300 mg/dL. - ️️After experiencing extreme fati...
