Blood Tests, Urinalysis, Faecal Testing, Cytology & Biopsy for Dogs and Cats
Dogs and cats cannot always communicate when something is wrong, and many illnesses produce symptoms that are difficult to distinguish through physical examination alone.
Veterinary laboratory testing provides additional information that can help identify medical abnormalities, evaluate organ function and support treatment decisions.
At Allpets & Aqualife Veterinary Clinic in Singapore, our diagnostic services include blood tests, urinalysis, faecal parasite testing, cytology and biopsy investigations.
The appropriate tests depend on each animal's symptoms, medical history, age and clinical assessment.
Why Do Dogs and Cats Need Blood Tests?
Veterinary blood tests measure different components of blood to provide information about an animal's health.
They may be recommended when investigating symptoms such as lethargy, vomiting, reduced appetite, unexplained weight changes or increased thirst.
Blood tests are also used in selected preventive health assessments, monitoring of chronic conditions and evaluations before medical procedures.
A blood test does not necessarily provide a complete diagnosis on its own. Results are interpreted alongside clinical findings and may indicate the need for additional investigations.
Types of Veterinary Blood Tests
Complete Blood Count (CBC)
A complete blood count measures and evaluates different types of blood cells.
These commonly include:
-
Red blood cells, which transport oxygen
-
White blood cells, which contribute to immune responses
-
Platelets, which play an important role in blood clotting
A CBC can provide information relevant to anaemia, inflammation, infection and selected blood disorders.
However, abnormalities are not always specific to one disease.
Blood Chemistry Tests
Blood chemistry tests evaluate substances such as enzymes, proteins, glucose, minerals and metabolic waste products.
They can provide useful information about selected aspects of liver and kidney function, blood glucose regulation, hydration and other metabolic processes.
Results outside a reference interval do not automatically confirm a particular disease.
Veterinarians interpret the findings based on the animal's medical condition and other results.
Electrolyte Testing
Electrolytes are minerals involved in maintaining fluid balance and normal physiological functions.
Measurements of substances such as sodium, potassium and chloride may be useful when investigating dehydration, vomiting, diarrhoea and certain metabolic disorders.
Additional Blood Tests
Depending on the clinical concern, veterinarians may recommend further tests for endocrine disorders, infectious diseases or other specific medical conditions.
Not every clinic performs every test on-site. Some samples may require analysis by an external laboratory.
When Should My Dog or Cat Have a Blood Test?
A veterinarian may recommend blood tests when a pet experiences:
-
Persistent lethargy or weakness
-
Increased drinking or urination
-
Reduced appetite
-
Unexplained weight loss
-
Repeated vomiting or diarrhoea
-
Suspected anaemia
-
Certain chronic medical conditions
-
Medical concerns identified during examination
Blood testing may also be considered before certain procedures involving anaesthesia or as part of an individualised senior pet healthcare plan.
The decision should reflect the pet's clinical circumstances and the information the test is expected to provide.
Urinalysis and Urine Testing for Dogs and Cats
Urinalysis is a laboratory examination used to assess urine characteristics and identify certain abnormalities.
It may include measurements of urine concentration, chemical constituents and microscopic examination of urine sediment.
What Can a Veterinary Urine Test Detect?
Urinalysis may provide information relevant to:
-
Urinary tract inflammation
-
Certain urinary infections
-
Kidney-related concerns
-
Glucose in the urine
-
Crystals and other sediment abnormalities
-
Problems affecting urine concentration
Additional tests, such as urine culture or diagnostic imaging, may be necessary depending on the findings.
How Is a Urine Sample Collected?
Veterinarians may obtain a urine sample through naturally passed urine, catheterisation or cystocentesis, which involves collecting urine directly from the bladder with a needle.
The most suitable collection method depends on the animal's condition and the intended laboratory tests.
For some investigations, a freshly collected sample is particularly important.
Faecal Testing for Dogs and Cats
Faecal testing examines a stool sample for evidence of selected intestinal parasites or other abnormalities.
It is commonly recommended when pets have persistent diarrhoea, gastrointestinal symptoms or suspected parasitic infections.
What Can Faecal Testing Identify?
Depending on the methods used, faecal investigations may help detect evidence of parasites such as:
-
Roundworms
-
Hookworms
-
Whipworms
-
Certain intestinal protozoa
Different organisms may require different diagnostic techniques.
A negative faecal examination does not guarantee that an animal is free from intestinal parasites because organisms or eggs may not be present in every sample.
How Should I Collect a Stool Sample?
A fresh stool sample should generally be collected in a clean, secure container.
Avoid contamination with soil, litter or other substances where possible.
Contact the clinic for instructions regarding sample quantity, storage and delivery, as requirements vary according to the planned test.
Cytology for Dogs and Cats
Cytology involves examining cells collected from tissues, fluid or other biological material.
It can help veterinarians investigate certain lumps, skin abnormalities, inflammation or suspected infections.
What Is Fine-Needle Aspiration?
Fine-needle aspiration is a sampling technique that uses a small needle to collect cells from a lump or abnormal area.
The collected material may be placed on microscope slides for cytological assessment.
Some procedures can be performed with minimal restraint, while others require sedation depending on the animal and sampling location.
Can Cytology Detect Cancer?
Cytology can sometimes identify characteristic tumour cells or suggest that a lesion may be neoplastic.
However, it may not provide a definitive diagnosis in every case.
Certain lesions require tissue biopsy and histopathology to establish their nature, assess tissue architecture or obtain information relevant to prognosis.
Biopsy and Histopathology for Pets
A biopsy involves collecting a tissue sample for microscopic examination.
Histopathology allows a pathologist to evaluate the arrangement and characteristics of cells within the tissue.
A veterinarian may recommend a biopsy when investigating:
-
Persistent or unusual skin lesions
-
Abnormal lumps or masses
-
Suspected tumours
-
Certain inflammatory disorders
-
Conditions requiring tissue-level confirmation
The biopsy technique, sampling site and need for sedation or anaesthesia depend on the suspected condition.
Samples may be submitted to an external veterinary diagnostic laboratory for specialist examination.
Cytology vs Biopsy: What's the Difference?
| Feature | Cytology | Biopsy and Histopathology |
|---|---|---|
| Sample | Individual cells or small groups of cells | Tissue sample |
| Common collection method | Needle aspiration, swab or impression | Tissue sampling procedure |
| Information provided | Cellular characteristics | Cellular and tissue architecture |
| Invasiveness | Often less invasive | Usually more invasive |
| Main limitation | May not provide a definitive diagnosis | Sampling and tissue interpretation still have limitations |
The veterinarian chooses the most appropriate method according to the clinical concern.
In some cases, both cytology and biopsy are used during an investigation.
Are Veterinary Blood Tests and Laboratory Tests Painful?
Blood collection typically involves a needle and may cause brief discomfort.
Urine collection, fine-needle aspiration and biopsy procedures vary in invasiveness.
Some investigations can be performed without sedation, while others may require pain management, sedation or anaesthesia.
Your veterinarian will explain the proposed method and any relevant risks before proceeding.
How Long Do Veterinary Laboratory Test Results Take?
Turnaround times depend on the type of investigation, sample quality, testing method and whether the sample is analysed on-site or sent to an external laboratory.
Some routine results may be available during or shortly after the appointment, while specialised testing, cytology or histopathology may take longer.
The clinic can provide an estimated timeframe based on the tests ordered.
How Much Do Dog and Cat Blood Tests Cost in Singapore?
Blood test charges vary according to the type and number of tests required.
A basic blood count, blood chemistry panel and specialised diagnostic investigation may involve different costs.
Consultation, sample collection and external laboratory charges may be billed separately.
Contact Allpets & Aqualife Veterinary Clinic for current pricing and clarification of the recommended testing.
How Much Do Cytology and Biopsy Cost in Singapore?
Charges depend on the sampling technique, anatomical site, sedation or anaesthesia requirements, laboratory analysis and complexity of the investigation.
A fine-needle aspirate and a surgical tissue biopsy are different procedures and may involve substantially different costs.
Ask the veterinarian for a breakdown of the proposed investigations and related charges.

Frequently Asked Questions
How often should dogs have blood tests?
There is no single testing interval appropriate for every dog. The need for blood tests depends on age, medical history, symptoms, medication use and veterinary assessment.
Does a normal blood test mean my dog is healthy?
Not necessarily. Some medical conditions do not cause detectable abnormalities on routine blood tests, particularly in their early stages. Other investigations may still be appropriate if symptoms persist.
Should senior cats have routine blood tests?
Selected screening tests may be useful for older cats, particularly where they have medical concerns or risk factors for age-related disease. A veterinarian can recommend an individualised monitoring plan.
Can a blood test detect kidney disease in dogs?
Blood chemistry testing can provide information relevant to kidney function, but results should be interpreted alongside urinalysis, medical history and other investigations. Some kidney conditions require additional assessment.
Can faecal testing detect all intestinal worms?
No. Detection depends on the parasite, testing method, sample quality and stage of infection. Additional sampling or other diagnostic methods may be recommended.
Is fine-needle aspiration the same as a biopsy?
No. Fine-needle aspiration generally collects cells for cytological examination, while biopsy collects tissue for histopathological assessment. The two methods provide different types of diagnostic information.
Does a lump always mean my dog or cat has cancer?
No. Lumps can have several causes, including inflammation, cysts, benign growths and malignant tumours. Veterinary assessment and appropriate sampling may be required to identify the cause.
Do pets need to fast before blood tests?
Some tests may require fasting, while others do not. Preparation depends on the investigation and the animal's health. Follow the clinic's instructions and do not withhold food or medication without veterinary advice.
