Summary

TLDRThis video demonstrates a laboratory procedure for observing blood clot retraction. The process starts with extracting blood and placing it in a tube, then waiting for an hour while monitoring the retraction of the clot. After one hour, the clot is carefully examined on a Petri dish for its consistency, which is found to be elastic. The results are compared by calculating the clot retraction percentage, with the final outcome being 26.6%. This procedure helps in understanding the blood clotting mechanism in patients.

Takeaways

😀 Blood sample is collected and placed into a tube for analysis.
😀 The sample undergoes retraction, which is then observed through the wall of the tube.
😀 The sample is allowed to rest for one hour to observe the clotting process.
😀 After one hour, the blood clot is carefully lifted and placed on a petri dish for inspection.
😀 The consistency of the clot is checked, and it is noted to be elastic.
😀 The clot's reaction is compared by measuring the volume difference between the original blood and the blood clot.
😀 The volume of the retracted clot is calculated by comparing it to the initial blood volume.
😀 For the specific case, the retracted clot volume is found to be 0.8 mL.
😀 The initial blood volume used for the sample is 3 mL.
😀 The retraction percentage is calculated as 26.67%, which is determined by dividing 0.8 mL by 3 mL and multiplying by 100.

Q & A

What is the first step in the procedure described in the transcript?
-The first step is to take a sample from the patient, which is then placed into a tube.
What is done after the blood is placed into the tube?
-After the blood is placed into the tube, it is subjected to retraction.
How long should the sample be left for after pouring it into the tube?
-The sample should be left for one hour after being poured into the tube.
What is done after the one-hour wait?
-After one hour, the blood clot is carefully lifted and placed in a petri dish.
What is observed once the blood clot is placed on the petri dish?
-The consistency of the clot is observed, and in this case, it is described as being elastic.
What is compared during the reaction test?
-The formation of the clot (after the blood clot is removed) is compared with the initial blood volume.
What is the volume of the clot retraction observed in this case?
-The clot retraction observed in this case is 0.8 milliliters.
How is the percentage of clot retraction calculated?
-The percentage of clot retraction is calculated by dividing the retraction volume (0.8 milliliters) by the initial blood volume (3 milliliters), then multiplying by 100%.
What is the result of the clot retraction calculation in this case?
-The result of the clot retraction calculation is 26.67%.
What is the final action described in the transcript after the clot retraction calculation?
-The final action is the mention of the pause, indicating a break in the procedure or observation.
