In the field of healthcare, the accuracy and reliability of the blood laboratory department are of paramount importance. A clean room that meets the standards is an essential prerequisite for ensuring the quality of blood tests. Today, let's delve into the construction standards of clean rooms in the blood laboratory department.

The air quality in the clean room directly affects the accuracy of test results. An efficient air purification and filtration system is indispensable, which can remove microscopic particles, bacteria, viruses, and other pollutants in the air. Generally, multi-stage filtration should be adopted, including primary, medium, and high-efficiency filters, to ensure that the air entering the clean room reaches an extremely high cleanliness standard.

For instance, in some advanced clean rooms of the blood laboratory department, HEPA (High-Efficiency Particulate Air) filters are used, with a filtration efficiency of up to 99.97%, effectively capturing particles with a diameter of 0.3 microns and above.

A suitable temperature and humidity environment is crucial for the preservation of blood samples and the normal operation of testing equipment. Usually, the temperature in the clean room should be maintained at 18 - 26°C, and the relative humidity should be controlled at 40% - 60%. Strict temperature and humidity control helps reduce sample deterioration and errors and ensures the stability of test results.

Just imagine, if the temperature is too high or too low, and the humidity is inappropriate, it may cause changes in the cells in the blood sample, thereby affecting the accuracy of the test.

To prevent external contaminants from entering the clean room and avoid cross-contamination between different areas, differential pressure control is crucial. A certain differential pressure should be maintained between the clean room and adjacent areas. Generally, the pressure in the clean room is required to be higher than that in adjacent non-clean areas. This ensures that air flows from areas with higher cleanliness to those with lower cleanliness, effectively blocking the invasion of contaminants.

For example, setting a reasonable differential pressure between the sample preparation area and the testing area in the blood laboratory department can prevent sample contamination during the transfer process.

Adequate and uniform lighting is crucial for the operations of laboratory technicians, while avoiding glare and shadows. Noise control can provide a quiet and comfortable working environment for laboratory technicians, reducing interference and errors.

Good lighting design allows laboratory technicians to observe samples and operate equipment more clearly, while a low-noise environment helps them concentrate, improving work efficiency and accuracy.

The walls, floors, and ceilings of the clean room should be made of materials that are easy to clean, do not generate dust, and do not accumulate dust. The surfaces should be smooth and flat, avoiding gaps and unevenness to reduce the possibility of bacteria growth and pollutant accumulation.

For example, the use of anti-static PVC floors and antibacterial wall coatings can effectively maintain the cleanliness and hygiene of the clean room.

Regular disinfection and cleaning are important means to maintain the cleanliness of the clean room. Strict cleaning and disinfection procedures should be established, effective disinfectants should be used, and it should be ensured that the cleaning tools themselves do not cause contamination.

By strictly implementing disinfection and cleaning measures, the presence of microorganisms and pollutants can be minimized, ensuring the safety and accuracy of blood tests.

The construction standards of clean rooms in the blood laboratory department are a comprehensive system, and each link is interrelated and mutually influential. Only by strictly adhering to these standards can a safe, accurate, and reliable environment be provided for blood testing work, safeguarding the health of patients.
