Parameters reported
These are the catalogue defaults. A laboratory can add, remove or rename parameters and set its own reference ranges to match the methods it actually runs.
| Parameter | Unit | Reference range |
|---|---|---|
| Bilirubin Total | mg/dL | 0.2-1.2 |
| Bilirubin Direct | mg/dL | 0.0-0.3 |
| Bilirubin Indirect | mg/dL | 0.2-0.9 |
This page does not interpret results
The ranges above are catalogue defaults and vary legitimately between laboratories depending on method, analyser and reference population. Age and sex change which range applies. Nothing on this page indicates what any particular result means — that is a clinical judgement for a qualified doctor who has your report and your history. 365LabPro is laboratory software, not a medical device, and it does not diagnose.
Frequently asked questions
What does the Bilirubin Total & Direct measure?
A bilirubin measurement reports total bilirubin together with the direct (conjugated) fraction, with the indirect fraction calculated as the difference between them.
Which sample is needed for Bilirubin Total & Direct?
This test is performed on a serum sample. The exact container and volume are set by the laboratory performing the test, so follow the instructions given at collection.
Are these reference ranges the same at every laboratory?
No. Reference ranges depend on the method, the analyser and the population the range was derived from, so two laboratories can legitimately publish different ranges for the same analyte. The range printed on your own report is the one that applies to your result.
How many parameters does this panel report?
This panel reports 3 parameters in the 365LabPro catalogue. A laboratory can add, remove or rename parameters to match its own methods.
