You opened your lab result and saw “Creatinine” with a number beside it. Maybe 1.4 mg\/dL. Maybe 2.7. Maybe higher. The lab printed a reference range, but no one explained what the number actually means or what to do next. This guide walks you through it, in plain English and in the Philippine context.<\/p>\n

What is Creatinine?<\/h2>\n

Creatinine is a waste product that your muscles produce constantly when they use energy. Healthy kidneys filter creatinine out of your blood and pass it into urine. When kidneys are working well, the amount of creatinine in your blood stays low and stable.<\/p>\n

When kidneys lose filtering power, creatinine builds up. So a high creatinine level is one of the earliest signs that kidney problems are present. It is not the only sign, but it is the easiest one to measure.<\/p>\n

Why Do Doctors Test creatinine?<\/h2>\n

A serum creatinine test (also called a blood creatinine test) is a single tube of blood drawn from your arm. The lab measures how many milligrams of creatinine are in each deciliter of blood (mg\/dL). It is one of the cheapest, fastest signals of kidney health.<\/p>\n
