Every test you add is read against the ones before it.

A PDF, a photo of the paper, or a screenshot of your portal. Every marker on it is read, and the ones you already have gain a line on the graph.

Newest first. The date is what the graphs plot against.

Date	Source	Analytes	Status

Only analytes present in two or more tests can be plotted. The band is the reference interval.

Read from the same values plotted above. Direction and range crossings only, over the span your tests actually cover.

Method

Each file is read once and the values extracted from it; the document itself is not stored. Values are compared against the reference interval for your age and sex, and a change is only called where the same analyte appears in more than one test.

Limitations

No specimen was collected or analysed by BloodMarker, and no value here has been verified against a laboratory record. A difference between two tests can come from the laboratory as easily as from you.
