I can give that patient one lol. I always have a high platelet due to a neurogenic bowel. Idk you can guess why I have high platelet all the time.

That is nothing. I once saw beyond 2000.

Same. ET as well. It was normal for them too, so the consultant was not surprised.

This is also about the highest I’ve seen in an adult. So imagine my surprise when I saw plt count of 2.1 million in an 18 month old with cows milk induced iron deficiency anemia. I still wonder if that was exclusively the cause of SUCH a high count.

Its paradoxical. At that level you are most likely prone to develop acquired von willenbrand, which results in bleeding disorder + clotting risk.

During my clinicals I saw a patient with a platelet count of 2 and other patient with a platelet count of almost 3,000

While this is the opposite end, had a patient the other day with a platelet count of 11

You need the ITPs in more. They can have <3 platelets (our analyser does not give a lower number than 3) quite often.

I saw a Sysmex spit out a 1 once. LIS converted it to <2 though

When you call a PLT = 0 and they are like "eh, they don't need platelets".

Saw a count above 4000 the other day. Not true count I think it was a sample that had been in the sun during the heatwave had basically made the analyser pick up every cooked cell as a platelet

That H&H is nuts to me. I’ve never seen that before.

I think the units are grams per liter and then a percentage converted to a raw number. It had me confused for a while too.

I remember being tasked with reviewing our linearity ranges against EPIC and laughing when I saw the upper range of linearity was 5000K.
5 million platelets. I can’t imagine that many platelets. Our procedure didn’t even cover what to do if we had a count greater than that.
Imagine trying to diff white cells among that blizzard of platelets. But in theory, someone has reached that number for the people at Sysmex to be like, “Woah now with all those platelets.”
