Which blood type has no antibodies? blood type antigens and antibodies chart.
Blood Culture Bottles are ALWAYS drawn prior to other labs to reduce contamination. . Tube MUST be filled 100% – No exceptions! NOTE: All tubes sterile. Standard order of draw: BLOOD CULTURES, royal blue, red, light blue, SST (Gold), green, tan, yellow, pink, pearl, lavender.
- First – blood culture bottle or tube (yellow or yellow-black top)
- Second – coagulation tube (light blue top). …
- Third – non-additive tube (red top)
- Last draw – additive tubes in this order:
The median cubital vein is the first choice for blood draws because it has a decreased proximity to arteries and nerves in the arm. The more lateral cephalic vein is the second choice and the basilic vein in the medial arm is the last choice.
Red top – Tube without gel separator, used mainly for serology and chemistry testing. 10mL Red top tubes are used in Blood Bank for antibody screens. c. SST / Gold top – Tube contains a clot activator / gel separator which separates the cells from the serum for a variety of testing.
In the era of lyophilized anticoagulants, order of draw is no longer important. Contamination of serum samples with K EDTA will occur routinely if order of draw is not followed. … Modern lab equipment can tell the difference between K from the EDTA tube and K from the patient, so order of draw is no longer important.
The order of draw is recommended for both glass and plastic venous collections tubes when drawing multiple specimens for medical laboratory testing during a single venipuncture. The purpose is to avoid possible test result error due to additive carryover.
The first step to the collection is to positively identify the patient by two forms of identification; ask the patient to state and spell his/her name and give you his/her birth date.
3.05. The most site for venipuncture is the antecubital fossa located in the anterior elbow at the fold. This area houses three veins: the cephalic, median cubital, and basilic veins (Figure 1).
Know Your Veins – A common choice for adult patients is the median cubital vein in the antecubital fossa (think crevice of the elbow). This vein is a good choice for beginners, as it’s close to the surface and tends not to roll when punctured. Some other commonly used veins are the basilic vein and the cephalic vein.
The cephalic vein is a safe secondary option if the median cubital vein is not working. This vein can be found along the upper arm to the thumb, but it is commonly drawn from the forearm or antecubital fossa area. Also found in the antecubital fossa, the basilic vein serves as a last resort for blood draws.
Yellow-top tube (ACD) This tube contains ACD, which is used for the collection of whole blood for special tests. NOTE: After the tube has been filled with blood, immediately invert the tube 8-10 times to mix and ensure adequate anticoagulation of the specimen.

Venipuncture. The median cubital vein in the antecubital fossa is the most commonly used site due to its accessibility and size, followed by the neighboring cephalic and basilic veins [13,49,51,52].
- Start with distal veins and work proximally. Start choosing from the lowest veins first then work upward. …
- Use a BP cuff rather than a tourniquet. …
- Apply the tourniquet correctly. …
- Puncture without a tourniquet.
I prefer to start IVs in the A.C. region (antecubital fossa). This is the area on the inner fold of the arm. Nurses may also start an IV in the veins on the forearm, back of the arm, or on the hand. Veins in the A.C. region are often larger, so it can be a preferred area when using a larger IV needle.
The cephalic vein runs along the ‘thumb-side’ of the forearm, whereas the basilic vein runs along the ‘pinky-side.
Lithium Heparin (Green-Top Tube)*: This tube is used for the collection of heparinized plasma or whole blood for special tests. *Note: After the tube has been filled with blood, immediately invert the tube gently several times to prevent coagulation.
Green top tube with sodium or lithium heparin: used for plasma or whole blood determinations. EDTA tubes: includes Lavender top, Pink top (used for blood bank testing), Tan top (used for lead testing), and Royal Blue top with EDTA (used for trace metal whole blood or plasma determinations).
Serum Separator Tube (SST) (Tiger Top): Does not contain an anticoagulant but contains a clot activator and serum separator gel. This tube is used for collecting serum.
- to obtain blood for diagnostic purposes;
- to monitor levels of blood components;
- to administer therapeutic treatments including medications, nutrition, or chemotherapy;
- to remove blood due to excess levels of iron or erythrocytes (red blood cells); or.
Venipuncture is the process of collecting or “draw- ing” blood from a vein and the most common way to collect blood specimens for laboratory testing. It is the most frequent procedure performed by a phle- botomist and the most important step in this proce- dure is patient identification.
The discard tube must be used to prime the tubing of the collection set, which will assure maintenance of the proper anticoagulant/blood ratio in the first tube filled. The discard tube should be a non-additive or a coagulation tube, and need not be completely filled.
