| description | The Borrelia IgG index is calculated using serum and CSF values for anti-Borrelia IgG, total IgG, and albumin. The anti-Borrelia IgG levels are normalized to total IgG and albumin for both CSF and serum, and these values are used to determine the CSF to serum antibody index ratio. | ||

| property | ACnc = Arbitrary Concentration | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Ser+CSF Ser = Serum CSF = Cerebral spinal fluid | ||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}.
