The term 'regenerative anemia' in veterinary hematology means the bone marrow is responding by releasing:

Accepted Answer

Immature red blood cells (reticulocytes)

The Knott's test concentrates and lyses red blood cells to allow microscopic identification of microfilariae in canine blood.

Question 4

Which urinalysis finding is MOST consistent with a urinary tract infection (UTI)?

Accepted Answer

Pyuria, bacteriuria, and hematuria

Answer

Pyuria (WBCs in urine), bacteriuria, and hematuria together strongly indicate an active bacterial urinary tract infection.

Question 5

When preparing a bone marrow aspirate for cytologic evaluation, which stain is routinely used?
