A preventive check-up is an essential part of taking care of your pet's health. It helps identify hidden diseases, assess the overall condition of the body, and take timely action. One of the key components of this check-up is laboratory tests, which provide objective information about the health of your dog or cat and prevent the development of dangerous conditions. In this article, we will review the tests included in a preventive check-up and explain why they are important.
Why Is It Important to Have Tests Even When Your Pet Appears Healthy?
Many diseases in animals develop without symptoms in the early stages. Pet owners may not notice problems until they reach an advanced stage. Tests help:
- Detect diseases in the early stages.
- Assess the function of internal organs.
- Monitor hormone levels and metabolism.
- Choose the right diet and preventive care.
- Detect parasites and infections.
Even if your pet looks healthy, annual tests will help ensure that everything is truly in order.
Main Types of Tests in a Preventive Check-up
1. Complete Blood Count (CBC)
What it shows:
- Hemoglobin and red blood cell levels (important for diagnosing anemia).
- White blood cell count (helps detect inflammation and infections).
- Platelet count (responsible for blood clotting). This test helps identify inflammatory processes, anemia, parasitic infections, and even oncological diseases.
2. Biochemical Blood Test
Assesses the function of:
- Kidneys (creatinine, urea).
- Liver (ALT, AST, bilirubin).
- Pancreas (glucose, lipase, amylase).
- Protein metabolism (albumin, total protein). This test is essential for the early detection of liver, kidney, diabetes, and other chronic conditions.
3. Urine Test
Helps assess kidney and urinary system function. Includes:
- Protein levels (may indicate inflammation or kidney issues).
- Glucose (important for diagnosing diabetes).
- Presence of blood (may indicate infection or kidney stones).
- Salt crystals (may suggest urinary tract disease). This test is especially important for cats, as they are predisposed to urinary tract diseases.
4. Stool Test
Conducted to detect parasites (worms, protozoa), dysbiosis, and digestive issues. The vet checks for:
- Presence of parasite eggs.
- Hidden blood (which may indicate internal bleeding).
- Gut microbiota balance. Even if your pet doesn’t go outside, it can still get infected through contaminated water or raw meat.
5. Parasite Test (Microscopy, PCR, or Rapid Methods)
Helps detect:
- Helminths (worms).
- Protozoan parasites (Giardia, Toxoplasma).
- Hematoparasites (tick-borne infections). This is especially important for animals that frequently go outside or interact with other animals.
Additional Tests Based on Indications
Sometimes the vet may recommend additional tests if certain diseases are suspected.
1. Hormonal Tests
Conducted when endocrine disorders are suspected, such as:
- Cortisol level test (diagnosis of Cushing's disease).
- Thyroid hormone test (important for diagnosing hypothyroidism and hyperthyroidism).
2. Blood Tests for Infections
May include tests for:
- Viral diseases (panleukopenia, calicivirus in cats, parvovirus in dogs).
- Dangerous bacterial infections (Borrelia, leptospirosis).
3. Skin Cytology and Smears
Ordered if the pet has skin issues, ear problems, or nasal discharge.
How to Prepare Your Pet for Testing?
To ensure accurate results, it's important to follow a few rules:
- Blood tests: your pet should fast (no food for 8–12 hours, but they can drink water).
- Urine test: collect the first urine in the morning in a sterile container.
- Stool test: the sample should be fresh (not older than 12 hours).
- If your pet is anxious, discuss the possibility of using calming medications with your vet beforehand.
How Often Should You Have Tests Done?
- Healthy young animals: once a year.
- Senior pets (7 years and older): twice a year, as age-related diseases develop more quickly.
- Animals with chronic diseases: as recommended by the vet (usually every 3–6 months).
Preventive check-ups and regular testing are the foundation of a long and healthy life for your pet. Even if your animal seems energetic, hidden diseases can develop unnoticed. Regular testing allows you to identify problems early and take action. Taking good care of your pet’s health will help prevent serious illnesses and extend their life.
