The phrase "arterial sample drawn at" is correct and usable in written English.
It can be used in medical or scientific contexts when referring to the collection of a blood sample from an artery at a specific time or location.
Example: "The arterial sample drawn at 10 AM showed elevated levels of glucose."
Alternatives: "arterial sample collected at" or "arterial blood sample taken at".
Blood gas samples were taken after arrival at hospital in only 122 (57%) patients, and of these only 23 (19%) were arterial samples drawn within 30 minutes of arrival.
Maternal and fetal arterial blood samples were drawn at timed intervals.
Arterial blood samples were drawn at baseline, 30 minutes, and 1 hour after ROSC.
Arterial blood samples were drawn at times 0, 30 min and 48 h, and analyzed using enzyme-linked immunosorbent assay.
Arterial blood samples were drawn at baseline, and at 5, 10, 15, 20, 30, 45 and 60 min. Plasma radioactivity was measured in each sample using a scintillation detector (automatic γ-counter; 1480 Wizard 3", Wallac, Turku, Finland).
Arterial blood samples were drawn at standard intervals throughout the study, and the absolute CMRglc measures (µmol/100 g/min) were calculated using Sokoloff's model with standard kinetic constants [ 15, 16].
The levels of IL-8 and MPO were measured in paired arterial and jugular samples drawn simultaneously at specific time points, using enzyme-linked immunoassay kits.
For the present study, only patients who had arterial blood samples drawn within 4 h after ICU admission were eligible for inclusion.
Arterial samples were drawn for blood gas analysis from the arterial line at baseline, at the end of the procedure with the bronchoscope still placed in the trachea, and 15, 30, 45, 60, and 120 minutes after removal of the bronchoscope.
In study 2, plasma arterial and jugular venous samples were drawn at predefined time points before, during (1, 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, and 120 hours), and after the infusion period (4, 12, 23, and 48 hours after the infusion).
