Low carnitene levels in skeletal muscle, liver, heart and kidneys result in decreased ability of these tissues to utilize long chain fatty acids as an energy source. Low levels indicate muscle carnitene deficiency with muscle weakness, or secondary carnitene deficiency associated with renal failure, cirrhosis and many other defects. Source: Regenstrief Institute

Carnitine is used to mean total carnitines, because historically total carnitine was measured by heating up the sample and breaking off the esters which provided pure carnitine. (Carnitine is also a single molecule which is described as free carnitine - with the acronym, C0). Aclycarnitine is not a single moiety but rather describes all of the esterified carnitines.
So Total carnitine = free carnitine(C0) + acylcarnitine = esterified + unesterified carnitine. Source: Regenstrief Help
