Leptospirosis Panel |
 |
| Specimen |
1 ml serum or 1 ml plasma |
 |
| Method |
Micro-agglutination (MAT) |
 |
| Schedule |
510 days |
 |
| Indication |
Tests for the presence of antibodies to L. canicola, L. icterohaemorrhagica, L.
grippotyphosa, L. hardjo, L. pomona, L. autumanalis, and L. bratislava. |
 |
Interpretive Guidelines |
Titers ò 1:250 suggest recent or current infection. A negative antibody result does not rule
out leptospirosis. During the acute phase, there may be little to no detectable antibody. If clinical signs persist,
suggest retesting in 2 weeks. Vaccination can cause positive titers. |
 |
| * S16514 |
Leptospira PCR |
 |
| Specimen |
3 ml urine or unfixed kidney tissue |
 |
| Method |
PCR |
 |
| Schedule |
714 days |
 |
| Comments |
Leptospirosis organisms are shed in the urine intermittently and so can be missed when a
single sample is tested. |
 |
Submission Instructions |
- 510 ml from 3 to 4 different days
- Spin down, pour off supernate, suspend sediment in normal saline (1 – 2 ml), refrigerate each sample.

 |
Interpretive Guidelines |
A titer >/= 1:64 suggests exposure or active infection. If result is borderline, we recommend
retesting in 3 to 4 weeks. Vaccination can give a positive result. |
