How low it is matters.
It may not effect your ticket but it can be very dangerous.

My wife had a condition called idiopatic thrombocytopenia(ITP)-translation-low platlets.
They do not know whay causes it(THAT"S the idiopatiic part)
She was on steroids for awhile and that didn't take care of the problem-for some people it does.
Sometimes it just goes away.

In our caseThey removed her spleen and poof all gone. Evidently when you have this there are antibodies on your platlets and your spleen being the good filter it is -- sees that and nukes them. The surgery was done orthroscopically and recovery was fast.

A hemotologist is the doc who handles blood disorders.

Low platlets can cause bleeding --not good.

I'm not a doctor I just play one on TV --LOL:
