MLT ASCP BOC EXAMINATION TEST 2025/2026 ANSWERS
AND QUESTIONS GRADED A+
✔✔Which of the following anthrax infections is also known as "woolsorter's disease"?
Cutaneous anthrax
Gastrointestinal anthrax
Inhalation anthrax
Injectional anthrax - ✔✔Inhalation anthrax
✔✔Inhalation antrax - ✔✔Woolsorters anthrax. Spores inhaled into lungs.
✔✔Cutaneous anthrax - ✔✔Endospores enter through a minor cut. 99% of all cases. A
small pimple or papule forms at the site of inoculation 2-3 days after exposure. A small
dark necrotic area known as an "eschar" forms.
✔✔Gastrointestinal antrax - ✔✔Ingestion of spores. Bloody diarrhea and other classic
GI symptoms
✔✔Injectional anthrax - ✔✔Direct injection of spores into tissue. The absence of an
eschar, and the fact that this form is much more severe (necrotizing fasciitis, organ
failure, shock, coma can occur) than cutaneous anthrax make it clinically distinct
✔✔The fibrinolytic system may be activated by which one of the following?
Streptokinase
Streptolysin
Fibrin
EDTA - ✔✔Streptokinase
✔✔Streptokinase - ✔✔exogenous activator produced by some bacterial species that
binds and activates plasminogen, a component of the fibrinolytic system
✔✔Streptolysin - ✔✔streptococcal hemolytic exotoxin that can cause hemolysis in
humans
✔✔Positive acid fast - ✔✔Red/Pink
✔✔Modified acid-fast stain - ✔✔Modified acid-fast stain uses carbolfuchsin as the
primary stain and a surface-active detergent to help the stain penetrate the waxy
material of acid-fast organisms. Acid-alcohol is the decolorizing agent and methylene
blue is used as the counterstain; used to stain *Nocardia*
✔✔Causative agent of antibiotic-associated pseudomembranous colitis - ✔✔Clostridium
difficile
, ✔✔Normal CSF - ✔✔Clear/colorless; 45-1000 mg/dL glucose; 15-50 mg/dL protein; 0-5
cells/mm3 WBC
✔✔Viral infection CSF - ✔✔Normal glucose, elevated protein, average 80 cells/mm3
with mononuclear cells
✔✔Purulent infection CSF - ✔✔Glocuse value less 45; protein value greater than 100;
WBC 800 CELLS/MM3. Glucose level is low because bacteria is using the glucose for
energy.
✔✔Tuberculosis/fungi CSF - ✔✔Glucose value low to normal; protein value less than 50
mg/dL; WBC 100 cells/mm3
✔✔Forensic toxicology - ✔✔Concerned with medical and legal implications of toxicants
✔✔Clinical toxicology - ✔✔Focuses on the relationships between xenobiotics and
disease states. This area emphasizes not only diagnostic testing but also therapeutic
intervention
✔✔Enviromental toxicology - ✔✔Enviromental chemical pollutants and their impact on
human health
✔✔Descriptive toxicology - ✔✔Uses the results from animal experiments to predict what
level of exposure will cause harm in humans.
✔✔Enterobius - ✔✔Pinworm - egg infects humans after ingestion
✔✔Taenia solium - ✔✔Pork tapeworm - cysticerus larva infects humans after ingestion
✔✔Trypanisma cruzi - ✔✔Does not have an egg stage and requires arthropod vector
✔✔Importance of irradiating blood - ✔✔To prevent transfusion-associated
✔✔What are the two general categories of nucleic acid amplification (NAA) techniques?
- ✔✔Target amplification and signal amplification
✔✔What are apolipoproteins? - ✔✔Proteins that bind lipids to form lipoproteins
✔✔What is the approximate time that should be allowed for samples to completely clot
before centrifugation for serum samples? - ✔✔20 minutes
✔✔All of the following are types of quality and process improvement tools, EXCEPT:
Six Sigma
Lean
