Question | Answer |

Why is diagnostic testing a useful tool for physicians | -establish diagnosis-monitor treatment progress-health promotoion-disease prevention-detect problem early-prompt treatment-establish baseline results-legal purpose-validate initial diagnosis-adjust/change treatment plan-provide info that pt is healthy |
homeostasis | a healthy body in the state of equilibrium or balance |
reference range | normal range; values expected for a particular test |
hematology | the science/study of blood/blood forming tissues; in a laboratory hematology deals with the processing and evaluation of blood and blood components |
hematologist | specializes in the diagnosis, treatment, prevention, and/or investigation of disorders primarily of the blood and lymphatic |
pathologist | examines tissue samples and interprets results; performs autopsies |
radiologist | specializes in the interpretation of the study of images of the human body |
critical values | need immediate attention, you need to be aware of critical values and how to read reports and note abnormal results |
CBC test typically includes | -RBC (red blood cells) -Hct (hematocrit) -Hb/Hgb (hemoglobin) -WBC (white blood cell) -Diff (differential blood count) -Platelet count |
process of matching blood is called | blood typing, crossmatching, or cross-typing |
What duties must an MOA perform to ensure pt understands everything they need to know about a dignostic test that has been ordered | -What will happen -What to expect -Where to go -How to prepare -How long will it take -How much discomfort is involved -Should anyone go with them -If any sedation is required -If they can drive after -any special aftercare instructions |
What information should a requisition include | -demographics -physician -health card number -any additional info -names of Dr.'s who should receive results -test required -indicate date/time of surgury (if booked) -specific reporting instructions -medications (if any, dose/frequency) |
What is the standard protocol when taking results over the phone | -repeat all recorded info back to caller -repeat pts name -test type and values -do not rush -read the values back -get name/number of caller -abnormal/critcal values, report to Dr. immediately |
What are positioning and draping used for | -facilitate an exam -allows access to a specific area -protects pts from embarrassment -modesty |
What are MOA's duties in diagnostic testing | -give out requisitions -educate clients -reporting/filing results -recognize/understand common ordered lab tests |
