Changes in Blood at Room Temperature| Changes in hematologic parameters
Summary
TLDRThis video explains the importance of storing blood samples at temperatures between 2 to 8 degrees Celsius. It highlights the adverse changes that occur when samples are kept at room temperature, including increased MCV and HCT due to swollen red blood cells, decreased MCHC and WBC, and a reduced ESR. Proper storage is crucial for maintaining sample integrity and ensuring accurate test results. The video encourages viewers to engage with the content by liking, sharing, and subscribing for more informative videos.
Takeaways
- 😀 Blood samples should be stored at 2 to 8 degrees Celsius for optimal preservation.
- 📈 MCV (Mean Corpuscular Volume) increases when blood samples are kept at room temperature.
- 🔴 RBCs (Red Blood Cells) swell at higher temperatures, affecting blood sample quality.
- 📊 HCT (Hematocrit) also increases as a consequence of the raised MCV.
- 📉 MCHC (Mean Corpuscular Hemoglobin Concentration) decreases when HCT is elevated.
- 👮♂️ WBC (White Blood Cell) counts decrease in samples stored at room temperature.
- 🧪 ESR (Erythrocyte Sedimentation Rate) drops due to swollen RBCs not settling properly.
- 🚫 Keeping blood samples at room temperature leads to compromised test results.
- 🕒 Proper storage is essential for accurate laboratory diagnostics and analysis.
- 👍 Always follow recommended storage guidelines to ensure sample integrity.
Q & A
Why is it important to store blood samples at 2 to 8 degrees Celsius?
-Storing blood samples at 2 to 8 degrees Celsius helps maintain their integrity and prevents changes in their composition that can occur at room temperature.
What happens to the Mean Corpuscular Volume (MCV) when blood samples are kept at room temperature?
-The MCV increases because red blood cells (RBCs) swell at room temperature.
How does the increase in MCV affect the Hematocrit (HCT)?
-The increase in MCV leads to a corresponding increase in Hematocrit (HCT).
What is the relationship between HCT and Mean Corpuscular Hemoglobin Concentration (MCHC) when blood is kept at room temperature?
-The MCHC decreases due to the increase in HCT, as the concentration of hemoglobin relative to the volume of red blood cells becomes lower.
What effect does room temperature have on White Blood Cells (WBC)?
-At room temperature, the count of White Blood Cells (WBCs) decreases.
Why does the Erythrocyte Sedimentation Rate (ESR) decrease when blood is not stored properly?
-The ESR decreases because swollen RBCs do not settle properly, affecting the sedimentation rate.
What could be the consequences of analyzing blood samples that have been improperly stored?
-Improperly stored blood samples can lead to inaccurate lab results, affecting diagnosis and treatment.
How can the changes in blood samples impact clinical decision-making?
-Changes in blood samples can mislead clinicians about a patient's condition, potentially leading to incorrect treatment decisions.
What should healthcare professionals do to ensure proper blood sample storage?
-Healthcare professionals should ensure that blood samples are promptly placed in controlled temperature environments between 2 to 8 degrees Celsius immediately after collection.
What is the overall message of the video regarding blood sample handling?
-The video emphasizes the critical importance of proper blood sample storage temperatures to maintain sample integrity and ensure accurate laboratory results.
