2. You have your Levey-Jennings Control chart ready. Your supervisor tells you to begin using the lot. Record the first 10 days of Control 1 Hemoglobin results. In your lab, you run controls once per day because you are a clinic open from 8- 5pm. Plot each data point on your labeled chart and circle whether the controls are acceptable or "out." Day 1= 4.5 mg/dl Day 6=4.8 mg/dl Day 2=4.2 mg/dl Day 7=4.4 mg/dl Day 3 =4.1 mg/dl Day 8=4.4 mg/dl Day 4=4.6 mg/dl Day 5=4.7 mg/dl Day 9=4.2 mg/dl Day 10=4.9 mg/dl ACCEPTABLE OUT OF CONTROL 3. You run a normal serum glucose control and obtain a value of 78.4 mg/dL. The mean for this control is 74.8 mg/dL and 1 SD has been calculated as 1.2. Is the value of 78.4 within 2SD (95% confidence interval). Show your work to determine if the value is within 2SD. Part 4: 3 pts each 1a. Your lab manager asks you to create the new control range for the new lot of hematology control level 1. The following 20 hemoglobin values are gathered to determine the control limits. Using a calculator or website SD function, calculate and record the mean, the standard deviation, and the 95% confidence interval for this set of values. 4.2 4.6 4.6 4.7 4.7 4.0 4.3 4.9 4.4 4.4 5.0 4.5 4.0 4.1 4.8 4.9 4.2 4.4 4.7 4.7 Mean: 1 SD: 95% Confidence range: 1b.
