Venipuncture hand site healed leaving a raised dark scar. Continuously picked it and the hard part came off. Now it's light with dark edges. Abnormal?
Do not pick: You may have a hypertophic scar or a keloid. It is not feasible to know without examining you. People of African ancestry are more to developing keloids. It is not an urgent issue and you could discuss it with your doctor at the next visit. In the meantime, do not pick at it, disturbing it will only make matters worse.
Many areas.: Venipunctures can be performed in many areas but the most common are in the veins in the hands or arms. Sometimes, in people whose veins are difficult to fine, veins in the groins (femora's) or even the neck (jugular) can be used.
The size of the vein: As dr. Placik said, venipuncture is for collecting blood through a needle from blood vessels that are big enough to see and/or feel. Capillary puncture would be used for collecting blood from vessels that are too small to see individually. This is usually done with a very small cut and a micro pipette or a piece of filter paper.See 1 more doctor answer
To test blood: Is this a school project? Venipuncture is a very common medical procedure to obtain blood for test. It can also be used for therapeutic reason, in cases such as iron overload.
Puncture vein: Venipunture is the process of puncturing a vein to gain access for drawing of blood (by aspirating with a syringe), inserting a catheter for IV purpose, or inserting a wire using seldinger technique to place a sheath. Direct puncture of the palpable vein is performed often using a tourniquet above the access site.
Varies: There is no set rule on the angle of entry. For smaller veins close to the skin, the angle is more acute with the needle/catheter closer to the skin. Deeper veins may require 45 degree angle, and larger angles make for more difficult entry as the tip may easily penetrate the back wall of the vein.See 1 more doctor answer
Blood test: Its taking blood out of a vein to do tests.
Few: In general venipuncture is safe, problem-free, and well-tolerated. Occasionally it may be associated with a poor sample quantity, more than expected discomfort, inability to access vein or obtain sample, hematoma, or the need to return for another sample attempt. Infection or other vascular issues are very rare.
Swelling/infection: During a mastectomy (removal of a breast due to cancer), a lymph node is removed from the armpit on the mastectomy side to be sure the cancer hasn't spread. In the past, removing 20+ nodes was common! Because the lymph nodes in the armpit fight infection, it wasn't uncommon for women to develop infections/swelling in that arm. So procedures, including blood draws, are limited to reduce infection.See 1 more doctor answer
