Moxie, I'm curious as to what was the time difference between the date of the 155 reading and the date of the 219 reading.

Cholesterol levels can vary by 15 percent from day to day. This is a range of 185-215 in just one day.

I take my Biscanner with me whenever I have a full lipid panel done at the lab. Just before I go into the lab, I take a Total and an HDL reading from the BioScanner as a comparative to what the lab resutls are.

In performing this method four times over a one year period, my BioScanner readings have always been within 5% of the lab results.

Some interesting data below:

The linearity of the BioScanner Cholesterol test system was tested using five levels of whole blood ranging from 83 to 424 mg/dL cholesterol. Each whole blood sample was run four times on the BioScanner.

The results are in the table below:

BioScanner Cholesterol Linearity Results
Reference Method / BioScanner

83 88
83 92
83 90
83 91
104 111
104 115
104 108
104 114
184 206
184 201
184 198
184 196
296 259
296 284
296 277
296 276
424 418
424 413
424 431
424 424

Fairly impressive accuracy and consistency against the standardized reference method.

The HDL tests show a % variation from the standard reference method of between 5.01% and 8.60% after 20 tests. This would equate to a difference of HDL 50 compared to HDL 46 in a worst case scenario.

I have found my readings to be very consistent. I have performed so many readings with my BioScanner and have developed such a confidence level that I would trust my readings over an off reading from a lab.
