A bilirubin level of 1.9 mg/dL is at the upper limit of the normal range, according to some sources. While several sources cite a normal total bilirubin range between 0.2 and 1.2 mg/dL, others include 1.9 mg/dL as the high end of normal. Therefore, a definitive answer depends on the specific laboratory's reference range.
Understanding Bilirubin Levels
Bilirubin is a yellowish pigment produced during the breakdown of red blood cells. High bilirubin levels can indicate underlying liver or other health issues.
Different sources offer slightly varying ranges for normal bilirubin levels:
- Source 1: 0.3 to 1.9 mg/dL (This source includes 1.9 as the upper limit of normal)
- Source 2: 0.2 to 1.3 mg/dL
- Source 3: 0.2 to 1.2 mg/dL (This is the most frequently cited normal range)
A level above 1.2 mg/dL is generally considered elevated by many sources, triggering further investigation. However, the context is crucial; a level of 1.9 mg/dL might be considered within the normal range depending on the laboratory's reference values.
What to Do if Your Bilirubin is 1.9 mg/dL
If your bilirubin level is 1.9 mg/dL, it's crucial to discuss this with your doctor. They will consider your individual health history, other symptoms, and potentially order further tests to determine the cause and any necessary treatment. A single isolated high reading doesn't necessarily indicate a serious problem.
