Normal potassium level in adults is 3.5–5.0 milliequivalents per liter (mEq/L) or millimoles per liter (mmol/L) so it isn't too much out of range. Medications, laxatives, and suppliments can affect the results.
As far as platelet count,a normal count is about 150,000 to 450,000 platelets per microliter (x 10–6/Liter) of blood so you are fine in that respect.
