The Levey-Jennings QC Chart for a test commonly performed in your office appears to suggest that the test is producing progressively higher results. How would you go about researching this phenomenon? What information should you present to the physician? 2. A test is showing systematically low results; that is, in each case, the result is proportionately lower than expected. The results are precise, but inaccurate. What must you do to ensure proper results? Document this appropriately in the QC log and in the patient s chart.

14 738 PART IV The Clinical Laboratory 3. You are performing a glucose test on your patient using a glucose meter. The patient s glucose result is below the level the meter can detect. The glucose meter can detect values as low as 40 mg/dl. What kind of value is this? What steps should you take with the test results? Using the space below, demonstrate recording this information in the patient s chart. 4. Patient Jacob Wisliki is on coumadin therapy following a stroke. Dr. Wilson requests that you maintain a flow sheet on this patient. Today is November 11, Mr. Wisliki s INR is 1.8. His current medication dose is 2 mg qd. Dr. Wilson orders weekly INR testing. Maintain Mr. Wisliki s flow chart using the information provided below. Mr. Wisliki s INR is below Dr. Wilson s target range today, so Dr. Wilson increases Mr. Wisliki s dose to 2.5 mg qd. You instruct Mr. Wisliki to return in a week as Dr. Wilson ordered. Mr. Wisliki returns. His INR today is 2.1. This is in Dr. Wilson s therapeutic range, but Dr. Wilson would like to see the value run higher. He increases Mr. Wisliki s dose to 3.5 mg qd. You instruct Mr. Wisliki to return in a week as Dr. Wilson ordered. Mr. Wisliki returns the following week. His INR today is 3.5. This value is higher than Dr. Wilson s therapeutic range, so he decreases Mr. Wisliki s dose to 3.0 mg qd. You instruct Mr. Wisliki to return in a week as Dr. Wilson ordered. Mr. Wisliki returns on schedule. His INR today is 3.1. Dr. Wilson is concerned that Mr. Wisliki s INR did not respond as usual to the decrease in the dose. He asks Mr. Wisliki about any changes in his diet. Mr. Wilson says that he has been eating more spinach lately because it is ripe in his garden. Dr. Wilson tells Mr. Wisliki that eating green leafy vegetables will cause the anticoagulant to not work as well in his body and can cause increased INR. He instructs Mr. Wisliki to avoid eating green leafy vegetables while on anticoagulant therapy. Dr. Wilson does not change Mr. Wisliki s dose as he expects the INR to go down when Mr. Wisliki stops eating as much green leafy vegetables. You instruct Mr. Wisliki to return in a week as Dr. Wilson ordered. Mr. Wisliki is back for his weekly INR check. Today his INR is 2.5. This is exactly where Dr. Wilson wants Mr. Wisliki s INR to be so he does not change his dose today. You instruct Mr. Wisliki to return in a week as Dr. Wilson ordered. Mr. Wisliki is back for his INR. Today his INR is 2.5. As Mr. Wisliki s INR is stable, Dr. Wilson does not change his dose. You instruct Mr. Wisliki to return in a week as Dr. Wilson ordered.
