Histopathology is where diagnosis happens. When a surgeon removes a tissue sample or a clinician takes a biopsy, the specimen goes to a pathology lab for examination under a microscope. The pathologist's report determines whether a tumour is benign or malignant, whether an infection is bacterial or fungal, and what treatment the patient needs next.

In Kenya, most hospitals and clinics do not run their own histopathology labs. Specimens get sent to a handful of reference laboratories, and in many cases, advanced work like immunohistochemistry (IHC) or molecular testing gets shipped overseas. That adds weeks to turnaround times and significant cost. CA Medlynks runs the full histopathology pipeline locally in Nairobi, from routine tissue processing through to NGS-based cancer genomics.

What Is Histopathology?

Histopathology is the study of diseased tissue under a microscope. A pathologist examines thin sections of tissue, stained to highlight cellular structures, and renders a diagnosis based on what they see.

The specimens come from two main sources. Biopsy specimens are small tissue samples taken from a patient during a clinical procedure, for example a punch biopsy of a skin lesion or a needle biopsy of a breast lump. Surgical specimens are larger pieces of tissue removed during an operation, such as a tumour excision or an appendectomy.

Histopathology is the standard method for diagnosing cancer. It also identifies inflammatory conditions (such as Crohn's disease or vasculitis), infectious diseases (tuberculosis granulomas, fungal infections), and autoimmune disorders. Without histopathological examination, many of these conditions cannot be confirmed.

Services Available at CA Medlynks

CA Medlynks offers four tiers of histopathology services, each building on the one before it.

1. Complete Histology

This is the foundation. Tissue specimens are fixed in formalin, processed through graded alcohols and paraffin embedding, sectioned on a microtome, and stained with haematoxylin and eosin (H&E). The resulting slides go to a board-certified pathologist for examination and reporting.

H&E staining is sufficient for the majority of routine diagnostic cases. It reveals tissue architecture, cell morphology, and most pathological changes. Every histopathology case starts here.

2. Immunohistochemistry (IHC)

When H&E staining alone cannot determine the type or origin of a tumour, IHC adds another layer of information. This technique uses antibodies that bind to specific proteins in tissue sections. The binding pattern tells the pathologist what type of cell the tumour is made of, where it originated, and in some cases, how it is likely to respond to treatment.

Common IHC applications include classifying lymphomas, distinguishing between primary and metastatic tumours, and testing for hormone receptors in breast cancer (ER, PR, HER2). IHC is also used to confirm diagnoses in difficult cases where morphology alone is ambiguous.

3. Molecular Pathology (PCR)

PCR-based molecular testing detects specific DNA or RNA sequences in tissue specimens. This is used for identifying infectious organisms, detecting gene mutations that guide cancer treatment, and confirming diagnoses at the molecular level.

At CA Medlynks, PCR results are typically ready within 7 hours. That speed matters when a patient is waiting for a treatment decision or when a surgeon needs intraoperative guidance.

4. NGS-Based Pathology

Next-generation sequencing (NGS) analyses hundreds or thousands of genes simultaneously from a single tissue sample. This is the most advanced level of pathology testing and is used primarily in oncology for tumour profiling, identifying actionable mutations, and matching patients to targeted therapies or clinical trials.

CA Medlynks operates NGS capabilities in-house. For research institutions and pharmaceutical companies, this means cancer genomics data generated locally in Nairobi without shipping specimens abroad.

The Referral Process

Sending specimens to CA Medlynks is straightforward. Referring facilities have two options.

  • Drop-off: Deliver fixed specimens directly to the CA Medlynks laboratory at Daykio Plaza, Ground Floor, off Ngong Lane, Nairobi.
  • Courier pickup: Request specimen collection from your facility. CA Medlynks arranges pickup with proper cold-chain and chain-of-custody documentation.

Each specimen must be accompanied by a completed request form that includes the patient's clinical history, the type of specimen, and the tests required. Proper labelling and fixation are essential for accurate results.

Results are delivered digitally via secure email. Physical copies are available on request. Referring clinicians can contact the reporting pathologist directly if they need clarification on findings.

The lab accepts referral specimens from hospitals, clinics, and research institutions across Kenya. You do not need to be in Nairobi to use the service.

Why Local Histopathology Matters

When specimens are sent overseas for advanced testing, the turnaround time typically stretches to 3 to 6 weeks. For a cancer patient waiting on a treatment plan, those weeks are not abstract. They are weeks without therapy.

Processing specimens locally in a KENAS-accredited laboratory (ISO 15189:2022) eliminates that delay. It also removes the logistical risks of international shipping: specimens lost in transit, customs delays, temperature excursions during transport.

The cost difference is significant too. International reference lab fees for IHC panels or NGS testing are typically 2 to 5 times higher than local rates, before adding shipping and handling charges.

CA Medlynks' pathologists are board-certified and available for direct consultation with referring clinicians. That kind of access does not exist when your specimens are in a lab on another continent.

Partnership and Volume Pricing

For hospitals, research institutions, and clinical trials that generate regular histopathology volumes, CA Medlynks offers partnership agreements with volume-based pricing. These agreements include dedicated account management, priority turnaround times, and customised reporting formats.

If your facility currently outsources pathology work overseas, or if you are setting up a clinical trial that requires local histopathology capacity, contact us for a custom quote.
