How long do cancer test results take for dogs?
In most cases, your veterinarian submits the biopsy samples to a veterinary laboratory, where a board-certified veterinary pathologist will evaluate them. It usually will take one to two weeks for the samples to be properly processed and examined, although results can sometimes be obtained faster.

How accurate is cytology?
Urine cytology is associated with a significant false-negative rate, especially for low-grade carcinoma (10-50% accuracy rate). The false-positive rate is 1-12%, although cytology has a 95% accuracy rate for diagnosing high-grade carcinoma and CIS. Urine cytology is often the test used for diagnosis of CIS.
How does dog cytology work?
Vaginal cytology is performed on female dogs during their estrus cycle to help determine the optimum time to breed and enhance the success of pregnancy. The types of cells present in the vagina vary depending on the stage of estrus. A swab is taken of the cells lining wall of the vagina and analyzed under a microscope.
Can cytology be wrong?
It’s much more common than you might have thought. The false-positive rate of endoscopic ultrasound fine-needle aspiration (EUS-FNA) cytology is thought not to exceed 1%.
Is histology better than cytology?
Histopathology focuses on the architecture of the tissue and provides more information about the tissue than cytology. With this type of laboratory examination, the accuracy of a diagnosis is usually high.
