Molecular
A linear DNA strand with one restriction enzyme recognition site will yield this many fragments.
What is 2?
These bacteria lack a cell wall (genus).
What is Mycosplama or Ureaplasma?
This laboratory value reflects the percentage of red blood cells in whole blood.
What is hematocrit?
One could expect to see these two clinically significant findings on the microscopic examination of urine with a positive nitrite and a positive leukocyte esterase.
What are bacteria and white blood cells?
To create a 1:10 dilution of serum, you would add 1 part of serum to this many parts of diluent.
What is 9 (parts).
List the correct order of the steps of a standard PCR cycle.
What is denature, anneal, extend?
The etiological agent of trachoma (genus and species).
What is Chlamydia trachomatis?
An increase in this white blood cell type is commonly seen in bacterial infections.
What is a neutrophil?
This cluster of capillaries acts as the kidney's primary "sieve," filtering plasma into Bowman's capsule.
What is the glomerulus?
This type of pipette can deliver variable volumes and is designed to be "blown out" to deliver the desired amount.
What is a serological pipette?
The yield of DNA from a sample with a concentration of 280 µg/mL and a volume of 0.5 mL.
What is 140 ug?
What is a photochromogen?
This screening coagulation test evaluates the extrinsic and common pathways and is used to monitor warfarin therapy.
What is the PT (prothrombin time)?
The Clinitest, based on the Benedict’s copper reduction reaction, is historically used to screen pediatric patients for reducing sugars. This specific reducing sugar is clinically significant in this population.
What is Galactose?
This type of QC error is characterized by a sudden, permanent change in the mean, often caused by a new lot of reagent or a bad calibration.
What is a systematic error? (would also accept “a shift”)
The specificity of the PCR reaction is determined by what component(s).
What are primers?
This genus is spread by the urine of infected animals and is considered zoonotic.
What is Leptospira?
Von Willebrand disease primarily affects platelet adhesion and this coagulation factor.
What is factor VIII?
Known as the "end-stage" of cast degradation, these highly refractive casts signify chronic renal stasis.
What are waxy casts?
This virus has the highest incidence of infectious risk in the clinical laboratory setting.
What is Hepatitis B?
This type of PCR begins with an RNA template rather than a DNA template.
What is reverse transcription PCR?
The vector associated with epidemic typhus.
What is the human body louse?
Failure of platelets to adhere to damaged endothelium due to absent GPIb receptors results in this disorder.
What is Bernard‑Soulier syndrome?
A fixed specific gravity of 1.010 in a patient across multiple samples is known by this term, indicating severe renal concentration loss.
What is isosthenuria?
A quality control material is determined to have a mean of 152 mg/dL and a standard deviation of 8. This range represents the 95% confidence limits for this level of quality control.
What is 136 – 168 mg/dL?
