The lifespan of RBCs
What is 120 days?
This is the process by which the body keeps clots from spreading indefinitely
What is fibrinolysis?
This lab test is used to monitor diabetics sugar control over the previous 3 months
What is hgb a1c?
This urine collection method is the best for obtaining bacterial cultures
What is a catheterized specimen?
A patient with colorectal cancer will likely have elevation in this tumor marker
What is CEA (carcinoembryonic antigen)?
Measurement of immature RBCs (lab test)
What is retic count?
Factors VIII, XII, XI, IX are part of this pathway of the clotting cascade.
What is the intrinsic pathway?
EKG changes suggestive of hyperkalemia
This test on a urine dipstick indicates the density of the urine and helps with evaluation of the concentrating and excretory ability of the kidneys
What is specific gravity?
Allergies, asthma, and parasitic infection may cause an increase in this type of leukocyte
What are eosinophils?
This type of anemia typically classically with low hgb, with high MCV, MCH, and RDW
What is megaloblastic anemia?
This test is used to monitor the clotting ability of factors along the extrinsic and common pathways.
What is PT/INR?
Positive Trousseau and Chovstek signs are suggestive of this electrolyte/mineral abnormality
What is hypocalcemia?
In a bacterial urinary tract infection, these two tests are usually positive
What are leukocyte esterase and nitrites?
Two fasting glucose readings over this number confirms diagnosis of diabetes
What is 126?
Basophilic stippling is seen with this condition
What is lead poisoning?
Degradation of clots will lead to an increase in this lab test.
What is d-dimer?
This liver enzyme is found predominantly in the liver and bone
What is ALP?
This type of bilirubin is water soluble and may be detected on a urinalysis
What is conjugated (direct) bilirubin?
A high number of these seen on microscopic urine exam is typically suggestive of a poorly collected or contaminated specimen
What are squamous epithelial cells?
A patient with bacterial pneumonia may have an increase in this type of leukocyte
What are neutrophils?
This factor is the catalyst that converts fibrinogen to fibrin
What is thrombin (IIa)?
This cardiac enzyme rises in 2-3 hours of injury, peaks at 14-24hr, and returns to normal around 10 days and is considered the "gold standard" of cardiac biomarkers
What is troponin?
These colorless bipyramid crystals may be seen in ethylene glycol poisoning
What are calcium oxalate crystals?
This disease should be suspected in a patient with prolonged bleeding but has a normal platelet count and normal PT/INR and PTT
What is vWD?
