ANA tests are performed to help diagnose these disorders
What are autoimmune disorders?
100
This nonsteroidal anti-inflammatory drug interferes with the cyclooxygenase enzyme, thus preventing platelet aggregation
What is Aspirin
200
This is the typical anticoagulant additive used for CBC blood samples.

A plasma protein that acts to salvage released hemoglobin so that its iron is not lost in the urine
What is Haptoglobin?
200
The increased volume of amniotic fluid after the first trimester
What is fetal urine?
200
An elevated lipase level indicates this pathologic condition

This coagulation factor is deficient in patients diagnosed with Hemophilia B
What is Factor IX?
300
This is the name for the liquid portion of blood once centrifuged when the tube does not contain an anticoagulant additive.
What is serum?
300
These cells are consistently found early in Megaloblastic Anemia
What are Hypersegmented Neutrophils?
300
A classic finding of synovial examination with the appearance cloudy, yellow-green color with 100,000 white blood cells (WBCs), a predominance of neutrophils, and a decreased glucose.
What is septic?
300
AST and ALT are both elevated in this condition.
What is Viral Hepatitis (hepatocellular disorders)
300
This specialized testing platform utilizes a laser to irradiate an isolated colonies to ionize the biomolecules and causing them to be accelerated into a flight tube for separation by mass-to-charge ratio
What is MALDI-TOF?
300
hypotension, nausea, flushing, fever and chills are symptoms associated with this type of transfusion reaction.
What is hemolytic?
300
The presence of Hepatitis B Surface antigen for greater than 6 months indicates this state
What is a “carrier” state?
300
This result is calculated and used to standardize the Prothrombin Time
What is the International Normalized Ratio (INR)?
400
This is used to graph successive run-to-run or day-to-day quality control data for monitoring laboratory test performance.
What is Levy-Jennings Chart
400
This condition is characterized by the presence of an elevated MCV, hypersegmented neutrophils, megaloblastic bone marrow findings, and autoantibodies to intrinsic factor.
What is Pernicious Anemia?
400
Identify this urinary microscopic element.
What is a waxy cast?
400
This enzyme is the first to become elevated when myocardial infarction occurs.
What is CK?
400
This organism was isolated from a urine culture on a MacConkey agar and swarming was observed on blood agar plate. This organism was a nonlactose-fermenter and positive for urease, tryptophan deamination, hydrogen sulfide production and K/A in triple sugar iron agar
