Can you draw blood with a 25 gauge needle?
While the size can vary, most needle sizes are 21 to 23 gauge. If a person uses the smaller-sized needles (such as 25 to 27 gauge), blood is more likely to get destroyed (hemolyze) or clot due to the smaller-sized needle.
Is a 25 gauge needle big?
The gauge size of a needle indicates what the diameter of the lumen (opening) is. The higher the gauge, the smaller the diameter. For example, a 30 gauge needle has a narrower lumen than a 25 gauge needle….Plastic (Tapered 1.25″)
| Gauge Size | Inner Diameter (mm) | Color |
|---|---|---|
| 25 | 0.280 | Red |
| 27 | 0.203 | Clear |
Can you draw blood from the forearm?
Learn more about the typical anatomy of the arm and hand when it comes to veins. For example, many people who perform blood draws will do so in the antecubital area of the arm (inner part of the forearm) where there are several large veins.
What gauge needle is used for blood draw?
21-gauge needles are the most commonly used for venipuncture, while 16-gauge needles are commonly used for blood donation, as they are thick enough to allow red blood cells to pass through the needle without being broken; In addition, the thicker caliber allows more blood to be collected or delivered in a shorter …
What is a 25 gauge needle used for?
Subcutaneous (Subcut) injections Inject at a 45-degree angle into fatty tissue overlying the triceps muscle — a 5/8″ needle, 23–25 gauge is recommended.
What is 25 gauge needle?

What is a 26 gauge needle used for?
These are regular-walled medical point needles. They are for intramuscular, subcutaneous, and other injections and are available in a wide range of gauges and lengths. They have an oversized chrome plated luer lock hub.
Which vein in the antecubital area should not be used for phlebotomy?
The cephalic and basilic veins have a greater tendency to roll and veinpuncture may be more painful from these sites. Sometimes venipuncture is performed on hand veins when the veins in the antecubital fossa are not appropriate. Blood is collected from the dorsal or back side of the hand (Figure 2).
What is Antecubital?
The median cubital vein (antecubital vein) is a prominent superficial upper limb vessel. This region of the upper limb is sometimes referred to as the antecubital area. The median cubital vein connects the cephalic and basilic veins, which are the two major superficial veins of the upper limb.
Is a 21 or 25 gauge needle bigger?
The gauge refers to the inner measurement or opening of the needle. In such cases, a gauge size with a LARGER number (eg, 25 G) may be preferred over a routine needle gauge (eg, 21 G) to minimize damage to the blood vessel, as well as minimize the associated pain with collection.
Which blood tube should always be drawn first when ordered?
EDTA tubes
The order of draw is based on CLSI Procedures and Devices for the Collection of Capillary Blood Specimens; Approved Standard – Sixth Edition, September 2008. This standard recommends that EDTA tubes be drawn first to ensure good quality specimen, followed by other additive tubes and finally, serum specimen tubes.
