What is the largest Mohr Pipet you can use to accurately pipet 0.5 mL of sample? 

Use the Potassium Laboratory Test Guide Below to answer the following Question: Laboratory Test Guide Test Name:  Potassium Specimen Type:  Blood Container:  Green top (Li Heparin tube), preferred  Alternate Tube: red, marble or gold top tube Specimen Processing:  Centrifuge specimen within 1 hour of collection and remove serum/plasma aliquot into a plastic sample container/cup Optimal Volume:  1 mL Minimum Volume:  0.2 mL Transportation/Storage:  Room Temperature Causes for Rejection:   Hemolysis, Lipemia, Bilirubinemia (icterus) Reference Range:  3.5 – 5.2 mmol/L Critical Values:  6.0 mmol/L   You are going to run a Potassium Assay on Blood Samples.  The Potassium Lab Test Guide above states causes for rejection include “hemolysis, lipemia, bilirubinemia”. State 2 other Specimen Quality Markers for Rejection that would cause a specimen to be rejected for this assay–in other words, other than the presence of interferents, why would a specimen be rejected for this assay?  State 2, if more than 2 answers are given then points will be deducted, regardless if they are correct.

You are validating a new assay to detect Influenza virus by a rapid antigen test.  You are comparing the results to culture results which is the gold standard and obtain the following results:   Positive for Influenza by Culture Negative for Influenza by Culture Positive for Influenza by rapid antigen test 500 50 Negative for Influenza by rapid antigen test 100 350   What is the Positive Predictive Value (PPV) for the new assay?

Reivew Day 19  on the Glucose October QC chart.  What does the plot indicate on this day?

You have run a batch of total proteins using a standard line made up of three standards: 3 g/dL, 5 g/dL and 8 g/dL.  The k factor of the standard line obtained is 0.0523.  The absorbance obtained for W896 is 0.510.  What total protein concentration should be reported out for sample W896?  

which of the following statements describes the differences between serum and plasma?

Exam Integrity Instructions: Before starting the exam, hold up your cell phone and tablet (if applicable) to the camera, then place them out of reach behind you. If you are wearing a smartwatch, put it on airplane mode or remove it for the duration of the exam. If using scratch paper, show both sides to the camera to confirm they are blank before beginning. **Failure to follow these instructions may result in a loss of points or a score of zero on the exam** T/F: I have performed this task(s) on camera

Lipemia appears as [physical] in serum/plasma due to [reason].

To properly use a volumetric pipet calibrated “to deliver” (TD), one should: *contents refers to the liquid inside the pipet
