Lab Literacy for Doctors: A Guide to Ordering the Right Tests for Better Patient CareChristopher Naugler, MD, FRCPC, Ethan Flynn, MD Lab Literacy for Doctors helps you make quick and efficient decisions about the right tests for typical clinical situations, thereby improving patient care. In a study published by the Journal of the American Board of Family Medicine (2014-03-01), primary care physicians reported that 15% of the time they are unsure about ordering lab tests and 8% of the time they are unsure about interpreting the results. This raises concerns about the need for more efficient and cost-effective lab test utilization. Lab Literacy for Doctors addresses these concerns in a practical, up-to-date, and easy-to-use format. Refer to this essential guide for: A quick index summarizing the clinical utility of common tests. Advice and information on lab errors, false positives and negatives, and blood and tissue collection. Sections on dermatology, ENT and respiratory system, endocrine system, fatigue, GI and hepatic system, gynecology and pregnancy, routine screening, and more. |
