Radium levels in samples collected at the facility were 200 times greater than samples taken upstream.
On the last day of each period, 6 arterial samples were collected at 45-min intervals.
Arterial blood samples collected from the carotid arteries of the rats at 4, 8, 24, and 72 h after PQ administration were analyzed using a standard blood gas analyzer (ABL 505; Radiometer, Copenhagen, Denmark).

To determine the blood lactate level at admission, an arterial sample was collected in the first 2 hours after a child's admission to the PICU.
Immediately after the intravenous injection of 11C-FLB 457, 18 arterial blood samples were collected at 10-s intervals over 3 min; the next 2 samples were collected at 60-s intervals over 2 min, and the remaining 10 samples were collected at longer intervals, for a total of 30 samples.
Arterial blood samples were collected at three specific times: on randomization before fluid administration, 6 and 24 hours after initial resuscitation.
To measure blood Tc-99m activity, 1.0 ml serial arterial blood samples were collected at 30-s intervals during the first 2 min and subsequently at 2, 4, 6, 8, 10, 20, 30, 60, and 120 min after injection.
Arterial blood samples were collected at the beginning and at the end of every two clearances.
