- Test Description
- Clostridium perfringens enterotoxin, Giardia (FA), Cryptosporidium (FA), Giardia ELISA
A panel that can be considered when suspecting Clostridium perfringens, Cryptosporidium spp., or Giardia spp. as the cause for gastroenteritis. Submission includes Cryptosporidium spp., Giardia spp. evaluated by FA, Clostridium perfringens enterotoxin assessment and a Giardia ELISA Antigen detection.
Note: The specimen must arrive cold (send on ice) and must be tested within 24-hours of collection for accuracy with regards to Clostridial enterotoxin detection.

Cryptococcal Antigen
- Test Code
- T550
- Results:
- 1-3 days
- Specimen
- • 0.5 mL serum in red top or serum separator tube
OR
• Cerebrospinal fluid in leak-proof transport tube - Test Description
- Used as a diagnostic test for Cryptococcosis. Detects the presence of Cryptococcal antigen.
Note: Serum and CSF submitted in a plain tube (white top or red top) are the only acceptable specimens. Plasma (any type) is not an acceptable specimen for this test. Body cavity fluid (e.g., CSF) cannot be submitted in a tube containing anticoagulant (e.g., LT) because the anticoagulant may invalidate the test.
-
Crystallographic Stone Analysis
- Test Code
- S16735
- Results:
- 1-5 days
- Specimen
- • Submit dry stone(s) collected in red top tube or in plain, sterile tube or container
- Test Description
- Nidus Composition, Stone Composition, and Shell Composition.
Antech’s stone analysis provides quantitative data on the composition of each stone, evaluating both the core (nidus) and outer layers. Reports include dietary recommendations to guide selection of the most appropriate nutritional profile for the patient, based on the stone’s specific mineral makeup. These insights support individualized dietary and lifestyle strategies to help minimize recurrence risk, as stone composition often reflects the patient’s diet and urinary chemistry.
Note: Stone submitted in formalin is not acceptable as formalin can affect the mineral composition.

Interferences: Prior to culture submission, patient should be off antibiotics for seven to ten days.
Note: When submitting samples from multiple sources, each culture source should be a separate submission: each with a sample (labeled accordingly with source) and a Test Requisition Form (TRF). When submitting fluid, place it in a RTT. Samples collected in EDTA are not acceptable. Submit tissue samples in RTT with a few drops of saline (to keep moist) and refrigerate prior to transportation to laboratory.

Culture, Aerobic (Blood)
- Test Code
- M060
- Results:
- 3-5 days.
- Specimen
- Whole blood collected in BD Bactec Blood Culture Bottle (BCB) with 1-3 mL whole blood added to bottle.
- Test Description
- This test is utilized when bacteremia with an aerobic organism is suspected. Submit a single sample in a BACTEC bottle.
Interferences: Antibiotics.
Note: Submit in BACTEC aerobic culture bottle. Clip fur and scrub venipuncture site for aseptic collection. Aim to collect 1.0 mL for cats and small dogs, 2‑3 mL for larger dogs to be inoculated into 20 mL bottle. Don’t unscrew caps on bottles. Remove the protective top and wipe visible parts of the rubber stopper with 70% ethanol. Allow stopper to air dry or wipe with sterile gauze. Replace the drawing needle with a sterile needle before puncturing the rubber stopper, fill until vacuum stops, then gently invert the bottle to mix. Anticoagulants in the media will prevent blood from clotting.
