Welcome to Bes Friends Pet Hospital, where our advanced diagnostic laboratory in Monrovia helps uncover answers quickly and accurately for your pet's health.
Diagnostic laboratory testing is a cornerstone of modern veterinary medicine. It includes a range of tests, such as bloodwork, urinalysis, and cytology, that allow our veterinary team to detect illness, monitor organ function, and guide treatment decisions.
At Bes Friends Pet Hospital, in-house veterinary diagnostics mean results often arrive the same day. This speed is crucial when pets are ill or when time-sensitive decisions are needed.
Routine diagnostics, like annual blood panels and fecal exams, help us spot issues early, even before your pet shows symptoms. Early detection leads to better outcomes and less invasive treatments.
Our diagnostic laboratory in Monrovia is equipped with the latest technology, so we can provide thorough, accurate answers for both preventive care and urgent medical concerns. Whether your pet needs routine monitoring or urgent diagnostic testing, our team is ready to help you make informed decisions for their well-being.

When your pet visits Bes Friends Pet Hospital for diagnostic laboratory services in Monrovia, you can expect efficient, compassionate care every step of the way.
Our veterinarians begin with a thorough physical exam and consultation. We discuss your pet's symptoms, lifestyle, and medical history to determine which diagnostic tests are appropriate for their needs.
Depending on your pet's condition, we may collect blood, urine, fecal, or tissue samples. Our veterinary professionals use gentle handling and low-stress techniques to keep your pet comfortable during the process.
We perform most tests in our on-site laboratory, including complete blood counts, chemistry panels, and urinalysis. For specialized or complex testing, we partner with trusted external laboratories to ensure accurate results.
Once results are available, our team explains the findings in clear, understandable terms. We discuss next steps, whether that means additional testing, treatment options, or routine monitoring, so you always feel confident in your pet's care plan.

Veterinary laboratory testing is vital for early disease detection, accurate diagnosis, and effective treatment planning. It helps our team catch hidden health issues and tailor care to your pet's unique needs.
Routine lab work can uncover underlying problems such as kidney disease, diabetes, or infections before visible symptoms appear, allowing for timely intervention and better outcomes.
Laboratory results help our veterinarians create precise treatment plans, monitor progress, and adjust medications or therapies as needed for optimal recovery and long-term health.
Knowing your pet's lab results provides reassurance and empowers you to make informed decisions about their care, especially when facing unexplained symptoms or chronic conditions.
Pets often hide signs of illness, making regular diagnostics essential. Contact our team if you notice any of the following:
