UNIT 1: Patient Hygiene — Importance & Overview
Patient hygiene is a fundamental pillar of safe and effective laboratory practice. In a medical
laboratory, maintaining patient hygiene not only ensures the accuracy of test results but also
protects both the patient and laboratory personnel from potential infections.
1.1 Definition of Patient Hygiene
Patient hygiene refers to the practices and standards maintained to ensure cleanliness, prevent
infection, and promote patient well-being before, during, and after a diagnostic procedure in a
medical laboratory setting.
1.2 Importance of Patient Hygiene
• Prevents cross-contamination between patients
• Ensures validity and accuracy of laboratory test results
• Reduces the risk of Healthcare-Associated Infections (HAIs)
• Maintains the dignity and comfort of the patient
• Complies with national and international healthcare regulatory standards
• Reduces the overall burden of hospital-acquired infections
• Protects healthcare workers from occupational exposure
1.3 Key Elements of Patient Hygiene
Patient Hygiene Elements
Hand Hygiene Patients should wash/sanitize hands before specimen collection
to prevent contamination
Skin Preparation The venipuncture or collection site must be cleaned with 70%
isopropyl alcohol
Clean Clothing Patients should wear clean attire; hospital gowns to be provided
if needed
Oral Hygiene For oral/throat swabs, patients advised not to eat/drink 30 min
before collection
Urinary Hygiene Mid-stream clean-catch technique taught to patients for urine
specimen collection
Personal Protective Patients with infectious conditions must wear masks during lab
visits
1.4 Pre-Analytical Hygiene Instructions to Patients

, BMLT Notes — Medical Laboratory Procedure & Infection Control | Rahul Kumar
1. Instruct patients to fast for 8–12 hours before fasting blood glucose or lipid profile tests
2. Patients should avoid strenuous exercise 24 hours before specimen collection
3. Patients must inform the technologist of any medications, supplements, or recent infections
4. Genital area should be cleaned before urine mid-stream collection
5. Patients must not apply lotions, creams, or nail polish on the collection site
Pre-analytical errors account for up to 70% of all laboratory errors. Most are
NOTE
preventable through proper patient hygiene education.
