Kreatinin er en forbindelse som produseres gjennom muskelmetabolisme og fungerer som en viktig indikator på nyrefunksjon. Den dannes fra kreatin, et molekyl som er essensielt for energiproduksjon i musklene, og filtreres fra blodet av nyrene før den skilles ut i urinen.
Testing creatinine levels is beneficial for several groups of people:
Elevated creatinine levels often indicate impaired kidney function. However, high creatinine itself usually doesn’t cause symptoms. Instead, symptoms arise from the underlying condition affecting the kidneys. These symptoms can include:
Improving carnitine levels generally involves dietary changes and, in some cases, supplementation:
Several factors can affect creatinine levels in the body, influencing either the production of creatinine or its filtration and excretion by the kidneys. These factors include:
