If I have high pct in blood test (1.700) this is some problem for my health or not that imortant? All other things are k only pct is high.

Procalcitonin. Ignore it. I think it's worthless to assay in healthy people. If it's rising and you're obviously sick, it's a marker for sepsis requiring more intense medical therapy. Some folks run high levels of these markers in health, and the reference ranges are set so that maybe 5% of healthy folks fall just above the top anyway.
