median 61 kIU/L (5th-95th centile: 2-889 kIU/L) in infants -69 to 31 days old median 1.2 kIU/L (5th-95th centile: 0.1-12.5 kIU/L) in infants 32 to 110 days old Levels of AFP in CSF decline with gestational age in proportion to levels of AFP in serum [ 19 ]

For example, on a certain monitor, the horizontal distance between the upper limits for parathyroid hormone in pmol/L and pg/mL may be 7 cm, with the mass concentration to the right. A molar concentration of, for example, 5 pmol/L would therefore correspond to a mass concentration located 7 cm to the right in the mass diagram, that is ...
