Plunger syringes designed to withdraw arterial blood samples. These devices typically consist of a 3 to 5 mL capacity syringe internally covered with heparin or heparin-based compounds (e.g., dry lithium heparin, sodium heparin) to avoid coagulation. The syringes are impenetrable by air and liquids to avoid blood and/or gas loss while transporting the sample; some include filters for air-bubble removal. Blood-sampling syringes are used to obtain samples for laboratory tests, including pH, blood gases (e.g., O2, CO2), electrolytes (e.g., calcium, magnesium, potassium, chloride), and/or metabolites such as lactate and glucose.
