Which of the following should be collected first for tests including CBC, chemistry panel, lead, and a toxicology screen via capillary puncture?

Choice A reason:
Occult blood detection is not a process that occurs naturally after a venipuncture to control bleeding. It is a laboratory test used to detect blood in the stool that is not visible to the naked eye. This test is unrelated to the venipuncture process.

Choice B reason:
The term "Phlebotomists" refers to healthcare professionals who perform venipuncture. It is not a process but a profession. Therefore, it does not fit the context of the question regarding the control of bleeding after venipuncture.

Choice C reason:
Hematopoiesis is the process of creating new blood cells in the body and occurs in the bone marrow. While it is an ongoing process essential for replenishing the body's blood supply, it is not directly related to controlling bleeding after a venipuncture.

Choice D reason:
Hemoconcentration is a condition where the blood concentration of cells and solids is higher than normal, usually due to a loss of plasma. This can occur during venipuncture if the tourniquet is left on for too long, but it is not a process used to control bleeding.

Choice A Reason:
Povidone-iodine is an antiseptic used for skin disinfection before and after surgery. It has a broad spectrum of antimicrobial activity, but it is not the preferred choice for capillary blood collection due to the potential interference with certain laboratory tests. Povidone-iodine needs to be completely dried to avoid hemolysis of the sample, which can affect test results.

Choice B Reason:
Hand sanitizer is generally used for hand hygiene and not for the disinfection of the site for blood specimen collection. While it is effective in killing germs on the skin, it contains emollients and gelling agents that can contaminate the blood sample and interfere with laboratory tests.

Choice C Reason:
70% isopropyl alcohol is the most commonly used disinfectant for aseptic technique in capillary blood collection. It is effective against a broad range of microorganisms and evaporates quickly, leaving no residue that could contaminate the sample. It is important to allow the alcohol to dry completely before performing the puncture to prevent stinging and sample dilution.

Choice D Reason:
A 10% chlorine bleach solution is not typically used for skin disinfection in blood collection due to its harshness and potential to cause skin irritation and damage. It is more commonly used for disinfecting surfaces and equipment in healthcare settings.
