Items starting with P

P1NP (serum procollagen type I amino terminal peptide; bone markers)

P1NP (serum procollagen type I amino terminal peptide; bone markers)

Adults: 27.7 – 127.6 ug/L

From 19/01/26, samples for P1NP will be analysed at QEHB.

Parathyroid Hormone (PTH)

Parathyroid Hormone (PTH)

New reference range in use from 3rd October 2022

2.7 – 11.1 pmol/L

(This reference range has been derived by assessment of literature and local data)

PTH should be interpreted in the context of calcium and albumin measurements. A PTH value inside reference limits in the presence of elevated corrected calcium values may indicate PTH excess.

Paroxetine

Paroxetine

Therapeutic range = 20 - 65 ug/L

Please contact the laboratory if paroxetine measurement is required for therapeutic monitoring purposes.

Paroxetine is measured by LC-MS/MS.

Plasma Viscosity - PV

Plasma Viscosity - PV

1.50 - 1.72 mPa

Clinical Decision Making Values

≤1.50 mPa LPV - PV indicates a subnormal level of plasma protein fraction.
>1.50 - ≤1.72 mPa NPV - PV result normal.
>1.72 - ≤2.00 mPa IDPV - PV result suggests Inflammatory Disease.
>2.00 mPa HPV - PV result suggests Monoclonal Gammopathy.
