What Happens in IVF Lab: A Glimpse

This blog consolidates those insights to offer a comprehensive overview of IVF lab essentials. It is designed to help embryologists and clinicians understand the foundation of a successful IVF lab, focusing on its components, setup, and holistic maintenance.

Understanding the Core Laboratory techniques of an IVF Lab

An IVF lab is more than just a workspace; it’s a controlled environment where science and precision intersect to create life. The lab’s design, equipment, and processes all play a pivotal role in ensuring optimal outcomes for patients.

Basic Components of an IVF Lab

1. Cleanroom Environment requirement for IVF Lab

Maintaining sterility and minimizing contamination are non-negotiable in an IVF lab. IVF lab planning needs a more professional process of designing, constructing and Validating IVF laboratories. A cleanroom ensures:

• Proper air quality with HEPA filtration systems.

• Positive air pressure to prevent external contaminants.

• Temperature and humidity controls for consistent conditions.

• ISO Class 7 Embryology Lab

• Total VOC level <500ug/M3

Key Equipment: HVAC systems, HEPA filters, particle counters.

2. Incubators specification for IVF Lab

Incubators are critical for creating a stable environment where embryos can develop. They regulate temperature, CO2, and humidity to mimic natural physiological conditions. Types of Incubators:

• Benchtop Incubators: Compact and suitable for individual embryos.

• Large-Chamber Incubators: Ideal for handling multiple cultures simultaneously.

• Time Lapse Incubators: provides a real uninterrupted culture environment where unlike static observation of Embryo growth at the time of maturity, fertilization, fragmentation, cell number, blastulation and aneuploidy can be observed through time lapse video.

Key Features: Dual gas control, rapid recovery times, and alarm systems.

3. ICSI Micromanipulation Area

This is where intricate procedures like Intracytoplasmic Sperm Injection (ICSI) are performed. Precision and stability are paramount.

Key Equipment:

• Inverted microscopes (Olympus, Nikon) with high magnification.

• Micromanipulators (Narishghe, Takanome, ON4, RI Integra) for handling gametes and embryos.

• Anti-vibration tables to ensure stability.

4. Cryopreservation Units- Cryocans and LN2

Cryopreservation extends the possibilities of IVF by allowing storage of gametes and embryos for future use.

Key Equipment:

• Liquid nitrogen storage tanks.

• Cryovials and goblets for safe storage.

• Programmable freezers for controlled-rate freezing.

5. Culture Media Preparation Area

The success of embryo culture depends heavily on the quality of the media used. This area is dedicated to preparing, storing, and testing culture media.

Key Features:

• Laminar flow hoods for sterile preparation.

• Refrigerators and freezers for media storage.

• pH and osmolality measurement tools for quality assurance.

6. Quality Control Systems for IVF Lab

Ensuring consistent lab performance requires robust quality control measures.

Key Actions:

• Routine calibration of equipment.

• Monitoring air and surface contaminants.

• Regular training and assessments for lab personnel.

Setting Up an IVF Lab: Dos and Don’ts

Dos:

1. Engage Experts Early: Collaborate with experienced embryologists and lab consultants during the planning stage.

2. Invest in Redundancy: Equip the lab with backup systems, such as spare incubators, spare Aspiration pump and power supplies.

3. Focus on Ergonomics: Ensure that the lab layout supports workflow efficiency and minimizes staff fatigue.

4. Establish Rigorous Protocols: Standard operating procedures (SOPs) ensure consistency and quality in lab operations.

Don’ts:

1. Cut Corners on Equipment: Inferior-quality equipment can jeopardize outcomes.

2. Neglect Environmental Controls: Failing to maintain optimal air quality, temperature, or humidity can compromise embryo development.

3. Overlook Staff Training: Continuous professional development is crucial for adapting to new techniques and technologies.

4. Ignore Maintenance Schedules: Routine maintenance is vital for the longevity and reliability of lab equipment.

Holistic Maintenance of an IVF Lab- Maintenance Protocols and SOPs

Maintaining an IVF lab is an ongoing commitment. Here’s how to approach it holistically:

1. IVF LAB Environmental Monitoring

Air Quality Control:

• Maintain Class 1000 air quality with a HEPA filtration system.

• Regularly monitor and control VOCs (Volatile Organic Compounds) using air samplers.

• Ensure proper HVAC maintenance to maintain stable temperature, humidity, and positive pressure.

• Using Air Filtration Equipment like CODA or Xander

Temperature and Humidity:

• Keep lab temperature between 20-24°C and relative humidity at 40-60%.

• Use calibrated environmental monitors to detect deviations.

Lighting:

• Use low-intensity, non-toxic lighting to minimize phototoxicity.

• Implement UV filters if necessary.
