1) Positive and negative controls atleast once per 24 hours
2) compare chemical readings among each other
3) Be aware of manufacturer limitations
4) Do not use DW water as negative controls as strips are designed for urine ionic concentration.
5) Additional control is run when strip integrity is questionable or when new bottle is opened.

Quality Control and Competency testing on your POC instrument. test is Hemoglobin, instrument is POC HEMOGLOBIN ANALYZER / ADULT / PORTABLE DIASPECT HEMOGLOBIN T EKF DIAGNOSTICS. Describe the manufacturer’s recommendations on how to perform QC procedures (what needs to be done, by whom and how often to achieve optimum results?). Describe what steps are needed when the QC fails. Describe competency testing required and indicate the recommended frequency. (Competency testing refers to an individual Tech’s ability to utilize the instrument.)

What are some potential impacts of the costs of quality related to Verizon’s extensive testing procedures, including impacts on manufacturers whose phones are not selected by Verizon to be sold to its customers?
7. A quality control engineer samples five from a large lot of manufactured firing pins and checks for defects. Unknown to the inspector, three of the five sampled firing pins are defective. The engineer will test the five pins in a randomly selected order until a defective is observed in which case the entire lot will be rejected). Let Y be the number of firing pins the quality control engineer must test. a) Find the probability distribution of Y. b)...
