Environmental Factors Affecting Blood Samples: Transportation and Storage Best Practices

Summary

• Temperature fluctuations can affect the integrity of blood samples during transportation and storage.
• Proper packaging materials must be used to protect blood samples from exposure to light and air.
• Humidity levels should be controlled to prevent degradation of blood samples.

Introduction

Transportation and storage of blood samples are crucial components of the diagnostic process in medical laboratories. The integrity of blood samples must be maintained to ensure accurate Test Results. However, environmental factors can impact the quality of blood samples during transportation and storage. In this article, we will explore how environmental factors such as temperature, light exposure, air, and humidity levels can influence the transportation and storage of blood samples in medical laboratories in the United States.

Temperature Fluctuations

One of the most critical environmental factors that can affect blood samples during transportation and storage is temperature fluctuations. Blood samples are sensitive to temperature changes, and exposure to extreme temperatures can lead to sample degradation. It is essential to transport and store blood samples at the recommended temperature to maintain Sample Integrity.

Impact of Temperature on Blood Samples

1. High temperatures can cause hemolysis, the rupture of red blood cells, leading to inaccurate Test Results.
2. Low temperatures can affect the stability of certain analytes, such as enzymes and proteins, in blood samples.

Best Practices for Temperature Control

1. Use temperature-controlled packaging during transportation to maintain the recommended temperature range for blood samples.
2. Store blood samples in refrigerated or freezer units with temperature monitoring systems to prevent exposure to extreme temperatures.

Light Exposure and Air

Exposure to light and air can also impact the quality of blood samples during transportation and storage. Light-sensitive analytes in blood samples can degrade when exposed to light, leading to inaccurate Test Results. Additionally, exposure to air can affect the stability of certain analytes in blood samples.

Protecting Blood Samples from Light Exposure

1. Use opaque packaging materials to protect blood samples from exposure to light during transportation.
2. Store blood samples in dark, light-proof containers to prevent light-induced degradation.

Preventing Exposure to Air

1. Use airtight containers or vials to store blood samples and minimize exposure to air.
2. Avoid air bubbles in blood sample containers to prevent oxidation and degradation of analytes.

Humidity Levels

Controlling humidity levels is essential to prevent degradation of blood samples during transportation and storage. High humidity levels can lead to moisture condensation in sample containers, affecting the stability of analytes. It is crucial to store blood samples in a controlled environment with optimal humidity levels to maintain Sample Integrity.

Optimal Humidity Levels for Blood Samples

1. Store blood samples in a dry environment with humidity levels between 30% to 50% to prevent moisture condensation.
2. Avoid storing blood samples in areas with high humidity, such as near water sources or in humid climates.

Conclusion

Environmental factors such as temperature fluctuations, light exposure, air, and humidity levels play a significant role in the transportation and storage of blood samples in medical laboratories in the United States. Proper handling and packaging of blood samples are essential to maintain Sample Integrity and ensure accurate Test Results. By following best practices for temperature control, protecting blood samples from light exposure and air, and controlling humidity levels, medical laboratories can optimize the quality of blood samples during transportation and storage.
