The level may be stated in pg/dL or pmol/L (sometimes abbreviated mmol/L); multiply by 0.1060 to convert from pg/dL to pmol/L.A US source states the average PTH level to be 8–51 pg/mL. In the UK the biological reference range is considered to be 1.6-6.9 pmol/L. Normal total plasma calcium level ranges from 8.5 to 10.2 mg/dL (2.12 mmol/L to 2.55 mmol/L). Interpretive guide
The intact PTH and calcium normal ranges are different for age; calcium is also different for sex. Model organisms
Model organisms have been used in the study of PTH function. A conditional knockout mouse line called Pthtm1a(EUCOMM)Wtsi was generated at the Wellcome Trust Sanger Institute. Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. Additional screens performed:  - In-depth immunological phenotyping

Baritosis is a benign type of pneumoconiosis, which is caused by long-term exposure to barium dust. Barium has a high radio-opacity and the disease may develop after few months of exposure. Extremely dense, discrete small opacities of 2–4 mm diameter, sometimes of a star-like configuration, are seen on the radiograph. Their distribution is uniform. When they are very numerous, superimposition may give the impression of confluency, but this does not seem to occur in reality. The hilar lymph nodes can be very opaque but not enlarged. After cessation of exposure, there is a gradual clearing of the opacities. Symptoms and signs
Cough
Wheezing
Nasal irritationIn some cases, it is asymptomatic. Diagnosis
The barium particles can be seen as opaque shadows on the chest X-rays of people with baritosis. However, being a benign condition, it neither interferes with lung function nor causes symptoms other than a mild cough.After exposure to barium dust ceases, the X-ray abnormalities gradually resolve.
