Acceptable Specimens During the First Week of Leptospirosis Include Which

Question

Acceptable specimens during the first week of leptospirosis include which of the following:
A) Cerebrospinal fluid (CSF)
B) Blood
C) Urine
D) A and B

Accepted Answer

During the first week of leptospirosis, the bacteria are typically present in the bloodstream and can also cross the blood-brain barrier, making both blood and cerebrospinal fluid (CSF) acceptable specimens for diagnosis. Urine is not typically useful for diagnosis in the first week as the bacteria tend to appear in the urine later in the course of the disease.
