Platelet Aggregometry (RIPA)

Ristocetin Cofactor Assay.
Measuring platelet aggregation.

- With Picmonic, get your life back by studying less and remembering more. Medical and Nursing students say that Picmonic is the most comprehensive and effective way to bridge learning and test prep...

Picmonic has hundreds of animated medical mnemonics...These are very interactive Picmonics that help you memorize and retain tons of medical topics.
They also have a mobile app so that you can learn and have fun on the run.

Platelet count is one of the lab tests used by a doctor or a hematologist to assess whether your platelet number is normal, low (thrombocytopenia) or high (thrombocytosis).

Bleeding 🩸 time (BT) is another test for platelet function.

ur impressions are the best
the animation is amazing
and ur efforts are unbelievable
Seriously thank you
i am joining hematology fellowship and i had no idea what ristocetin is
and i am treating VWD patients without understanding the pathophys
ur a hero

[AhmedMohamed-jre]

This channel is a treasure, thank you very much for your effort ❤️❤️

[jihannnabilla]

Im a medical technology laboratory's student. This video help me so much in hematology lesson
Thank you so much for your great video ♥️
I'll wait for another great video 😅😁

[markoprazetina]

Great video, but Ticagrelor is an orally administered direct-acting P2Y12-receptor antagonist and not Gp IIb/IIIa antagonist as mentioned in 02:14.

Hairy Cell Leukemia! Thanks for the video! I finally understood this damn thing 😂

[raushansingh]

Ur videos are awesome, I watched all ur hematology section videos and ans of ur last question I think is Hairy cell Leukemia becoz this TRAP is also useful to distinguish hairy cell leukemia with other B cell lymphomas..

[rehabhh]

What is your subspeciality? I really start to love heamatology when you make it easy ..I wish you can explain ECG ..if not who is the one I can listen to in explaining ECG

[dusk]

A lot of thanks!

It’s hairy cell leukemia

Dear Medicosis! Thanks for the great lecture as usual!
The only thing I could never fully understand about RIPA💉: why does it show normal result in Glanzmann Thrombasthenia? How can normal aggregation occur if there is no actually normal interaction between GpIIbIIIa and fibrinogen receptor? Even if previous step (interaction between GpIb and vWF) is normal, the further step seems to me disturbed...
And if GpIb and vWF interaction is enough for good or normal aggregation, so why is the bleeding time prolonged in Glanzmann?

im so happy. i learned a lot again today. hema can be a son of a B but u make it easier. also i think the graph was incorrect cause it should start with a high OD? i don't know. EDIT: AHHHH so you used light transmitted for the Y axis instead of the OD?didn't notice that. also...TRAP positive cells are seen in hairy cell leukemia because they're the only cells resistant to tartrate staining

Won't aspirin therapy affect the second wave which needs the granules to be released

[alcelynpedrique]

Dear Medicosis, I love your lectures and presentations. However, if I may say, please slow down a little. Thank you!

[manu]

Love your explanation n please make lectures on Ristocetin co factor assay and coagulation assays..

[manarsmaan]

Thank you so much for the greatest explanation ever for RIPA . Is there a one vedio for all diseases together represented by RiPA .

[felipemachado]

Amazing lectures!!!
What's the best way to measure aspirin efficacy?

[hebaahmed]

Thanks for your videos.how is aggregometry using epin, ADP, .. normal in BSS.there is no adhesion to aggregation occurs.

[yusufsediqi]

Thank you for the video. Why does desmopressin (ddavp) work for BS when the problem is gp1b and ddavp increases expression of vwf not gp1b? Best wishes. Yusuf

[saifakib]

Nice video on a uncommon topic. Is this important for step 2 ck?

[Sara-qvjz]

I need a video about hepatic enchephalopathy please🤔
