Pre-employment medical screening is a fundamental part of the hiring process in Kenya, serving to protect both employers and employees by ensuring that workers are medically fit for the duties they will perform. Under Kenya's Occupational Safety and Health Act (OSHA) 2007, Section 103(7), employers are required to arrange pre-employment, periodic, and post-employment medical examinations for their workers. Whether you are an employer seeking to meet your legal obligations or a job seeker preparing for a medical exam, this guide explains everything you need to know about occupational health screening in Kenya.
Legal Framework: OSHA Kenya and Workplace Health Regulations
Kenya's occupational health landscape is governed by several laws and regulatory bodies. The cornerstone legislation is the Occupational Safety and Health Act (OSHA) 2007, which mandates that employers must require medical examinations at key employment stages: before hiring, at regular intervals during employment, and upon termination of service.
The Directorate of Occupational Safety and Health Services (DOSHS), housed under the Ministry of Labour, administers and enforces workplace health regulations across the country. DOSHS works alongside other key regulatory bodies including:
- OSHIBA (Occupational Safety and Health Injuries Benefits Authority) – Manages workplace injury compensation
- KEBS (Kenya Bureau of Standards) – Sets workplace environment standards
- County governments – Issue food handler certificates and enforce local health regulations
A new draft Occupational Safety and Health Bill 2024 is currently under public participation, which aims to modernise and strengthen the regulatory framework for workplace health and safety in Kenya.
Under OSHA Kenya 2007, Section 103(7), employers are legally obligated to require pre-employment, periodic, and post-employment medical examinations. Non-compliance can result in penalties and legal liability.
Who Needs Pre-Employment Medical Screening?
While all employers in Kenya are encouraged to conduct pre-employment medicals, certain industries are legally required to do so. These include:
- Mining and quarrying (Class A work permits) – Workers exposed to dust, chemicals, and physically demanding conditions
- Construction – Workers operating heavy machinery or working at heights
- Food handling – All employees involved in food preparation, processing, or service require a food handler's medical certificate issued by county governments
- Aviation – Pilots, cabin crew, and ground staff require aviation-specific medical clearance
- Healthcare – Medical professionals and support staff working in clinical environments
- Manufacturing with chemical exposure – Workers handling hazardous substances, solvents, or industrial chemicals
Work Permit Medical Examinations for Foreign Nationals
Foreign nationals seeking employment in Kenya must undergo a medical examination as part of the work permit application process. Medical examination reports are submitted through the eFNS Portal (https://fns.immigration.go.ke) and a Certificate of Good Health is required for all work permit classes, including Class A (mining), Class D (general employment), and others. The medical report must be completed by a registered medical practitioner in Kenya and typically includes a general physical examination, chest X-ray, and blood tests.
What Does a Pre-Employment Medical Exam Include?
The scope of a pre-employment medical examination varies depending on the industry and job requirements, but a standard screening typically covers:
Basic Physical Examination
- General physical assessment including height, weight, BMI, and vital signs
- Vision testing (visual acuity, colour vision where applicable)
- Hearing assessment (audiometry for noise-exposed roles)
- Cardiovascular examination
- Respiratory assessment and lung function testing
- Musculoskeletal evaluation
Laboratory Investigations
- Complete Blood Count (CBC) – Screens for anaemia, infections, and blood disorders
- Blood sugar (Fasting or Random) – Screens for diabetes
- Liver Function Tests – Important for roles involving chemical exposure
- Kidney Function Tests – Creatinine and BUN levels
- Urinalysis – Screens for kidney disease, diabetes, and substance use
- Chest X-ray – Required for food handlers and roles with dust exposure
- Drug screening – Increasingly required in safety-critical roles
Additional Screening Based on Role
- HIV testing – Available through the VCT@WORK initiative for voluntary workplace HIV testing, though mandatory HIV testing as a condition of employment is prohibited under Kenyan law
- Hepatitis B and C screening – Required for healthcare workers and those with blood exposure risk
- Heavy metals testing – For workers in mining, manufacturing, and chemical industries
- Spirometry (lung function) – For roles involving dust, fumes, or respiratory hazards
Workplace Mental Health in Kenya
Mental health is an increasingly recognised component of occupational health in Kenya. In 2023, the Ministry of Health published the National Guidelines on Workplace Mental Wellness, providing employers with a framework for promoting psychological well-being in the workplace. While mental health assessments are not yet a mandatory part of pre-employment screening, forward-thinking employers are incorporating psychological wellness evaluations into their occupational health programmes.
Health Insurance Coverage for Occupational Screening
Since October 1, 2024, Kenya's Social Health Authority (SHA) replaced the former NHIF. The new Primary Healthcare Fund (PHF) under SHA now covers basic diagnostic tests for all citizens regardless of contribution status. This means that many of the laboratory tests included in pre-employment screening may be accessible through the public health system, though most employers opt for private laboratory services to ensure faster turnaround and comprehensive reporting.
Employer Wellness Programmes
Beyond regulatory compliance, many Kenyan employers are investing in comprehensive workplace wellness programmes. The Federation of Kenya Employers (FKE) operates wellness networks in Nairobi, Mombasa, Eldoret, and Laikipia, reaching over 150,000 employees with health education, screening, and referral services. These programmes go beyond basic pre-employment screening to include periodic health check-ups, workplace ergonomics assessments, and occupational disease surveillance.
How to Prepare for Your Pre-Employment Medical
If you have been asked to undergo a pre-employment medical examination, the following preparation tips will help ensure accurate results:
- Fast for 8–12 hours before the appointment if blood sugar or lipid testing is required
- Bring your national ID or passport and any previous medical records
- Disclose all current medications and supplements to the examining doctor
- Get adequate rest the night before to ensure accurate blood pressure and heart rate readings
- Avoid alcohol for at least 24 hours before the examination
- Bring your prescription glasses or contact lenses if you wear them for the vision test
- For work permit applicants: Ensure you have your passport and eFNS Portal reference number ready
