  1. Complete Blood Count (CBC)
    • Detects anemia, infections, and immune deficiencies.
  2. Liver Function Tests (LFT)
    • Checks for hepatitis, medication-induced liver damage.
  3. Kidney Function Tests (KFT)
    • Monitors kidney health for chronic diseases.
  4. Fasting Blood Sugar (FBS) & HbA1c
    • Screens for diabetes and metabolic disorders.
  5. Lipid Profile (Cholesterol, Triglycerides)
    • Assesses risk for heart disease and stroke.
  6. Urine Analysis
    • Detects urinary tract infections, kidney disease.

C. Infectious Disease Screening

Healthcare workers are at high risk of exposure to infectious diseases, requiring routine immunization and testing.

  1. Tuberculosis (TB) Screening
    • Mantoux Test / IGRA (Interferon-Gamma Release Assay)
    • Chest X-ray (for high-risk individuals)
  2. Hepatitis B & C Screening
    • Hepatitis B Surface Antigen (HBsAg)
    • Anti-HCV Test for Hepatitis C
  3. HIV Test
    • ELISA or rapid test for early detection
  4. COVID-19 Antibody Test
    • Determines previous exposure or immunity level.
  5. Respiratory Virus Panel
    • For employees in ICU, emergency departments, or infectious disease wards.

D. Occupational Health Screenings

  1. Radiation Exposure Monitoring (For Radiology & Nuclear Medicine Staff)
    • Annual dosimeter readings to track radiation exposure.
    • Eye and thyroid function tests.
  2. Hearing Test (Audiometry)
    • Essential for workers exposed to high noise levels (e.g., in operating rooms, ICUs).
  3. Lung Function Test (Spirometry)
    • Required for healthcare workers exposed to anesthetic gases, chemicals, and disinfectants.
  4. Vision Test (Optometry)
    • Checks for eye strain, refractive errors, especially for professionals working with screens, microscopes, or radiation equipment.
  5. Ergonomic and Postural Assessment
    • Prevents musculoskeletal disorders in nurses, physiotherapists, and surgeons.

E. Mental Health and Well-Being Assessment

  1. Burnout and Stress Screening
    • Assess workplace stress, anxiety, and emotional exhaustion.
    • Includes psychological counseling and wellness programs.
  2. Depression and Anxiety Screening
    • Patient Health Questionnaire (PHQ-9) for depression.
    • Generalized Anxiety Disorder (GAD-7) screening.
  3. Sleep Disorder Evaluation
    • Shift workers and night-duty staff are prone to sleep deprivation.
    • Screening for sleep apnea, insomnia, and fatigue management.

F. Immunization and Booster Shots

Annual health check-ups ensure healthcare workers are up to date with the required vaccinations.

VaccineRecommended Schedule
Hepatitis B3 doses + antibody titer check
InfluenzaYearly
COVID-19As per national guidelines (including boosters)
Tetanus, Diphtheria, Pertussis (Tdap)Every 10 years
MMR (Measles, Mumps, Rubella)2 doses if not previously vaccinated
Varicella (Chickenpox)2 doses if not immune
MeningococcalFor microbiology and emergency staff
BCG (Tuberculosis)If working in TB-infected zones
