What are the errors that occur in blood collection?

What are the errors that occur in blood collection?

Common errors in blood sample collection include in- correct identification, wrong tube, insufficient sample quantity, clot- ting, hemolysis, and contamination. Unlike some other errors, mislabel- ing of blood samples is 100% pre- ventable.

What is the most common complication encountered in obtaining blood specimen?

Results: Minor bruising and hematoma were fairly common, involving 12.3% of venipunctures, with minor bruising being the most common reaction. Serious complications were observed in 3.4% of patients. Diaphoresis with hypotension occurred in 2.6%. Syncope occurred in less than 1% of patients.

What are 3 complications that can occur with a venipuncture procedure?

Complications that can arise from venepuncture include haematoma forma- tion, nerve damage, pain, haemaconcentration, extra- vasation, iatrogenic anaemia, arterial puncture, pete- chiae, allergies, fear and phobia, infection, syncope and fainting, excessive bleeding, edema and thrombus.

What is the major cause of specimen rejection *?

The most common reasons for specimen rejection were contamination (n=764, 35.1%), inappropriate collection container/tube (n=330, 15.2%), quantity not sufficient (QNS) (n=329, 15.1%), labeling errors (n=321, 14.7%), hemolyzed specimen (n=205, 9.4%), and clotted specimen (n=203, 9.3%).

Why would a collection tube loose vacuum?

If the vacuum tube is not filling properly, and you are certain that you have entered the vein properly, substitute another tube. Occasionally, vacuum tubes lose their vacuum. If the specimen cannot be properly collected, select another site and using new, sterile collection equipment, collect the specimen.

What is a possible consequence of not properly identifying the patient with blood specimen collection?

mislabeling costs the average hospital $2700/month; 11% of transfusion deaths are caused by phlebotomists failing to properly identify the patient or the sample; hospital sample/patient ID error rates range from 0.1% in one study to 5 percent in another.

What is the most common phlebotomy complication?

Hematoma: The most common complication of phlebotomy procedure.

What is the most common adverse reaction from a patient when drawing blood?

The most frequent adverse events include haematoma,a vasovagal reaction or faint, and a delayed faint.

What are venipuncture complications?

Complications that can arise from venepuncture include haematoma formation, nerve damage, pain, haemaconcentration, extravasation, iatrogenic anaemia, arterial puncture, petechiae, allergies, fear and phobia, infection, syncope and fainting, excessive bleeding, edema and thrombus.

Why would a lab reject a blood sample?

The reasons for rejection are mostly following: incorrect test request (53.6 %) and hemolysis (22.6 %) in the biochemistry samples, inadequate sample (61.5 %) and incorrect test request (30.2 %) in hormone samples, clotted samples (76.9 %) and incorrect sample container (7.9 %) in hemogram samples, level error (38.5 %) …

Why do blood tests get rejected?

Incorrect sample types received: Basic incorrect blood tube/other sample. Samples without the appropriate preservative (e.g. acidified urine samples). Samples that are received ambient, when a frozen sample is required.

What is vacuum blood collection?

A Vacutainer blood collection tube is a sterile glass or plastic test tube with a colored rubber stopper creating a vacuum seal inside of the tube, facilitating the drawing of a predetermined volume of liquid. Vacutainer tubes were invented by Joseph Kleiner and Becton Dickinson in 1949.

How has the use of blood collection tubes changed over time?

Thus, the evolution of blood collection tubes have improved specimen quality and workflow efficiency as well as the safety of patients and health care workers. Glass evacuated tubes containing anticoagulants were commonly used from the 1950s to the 1990s (4).

How do you handle a blood specimen after collection?

Specimen handling. Allow whole blood to clot at room temperature for a minimum of 30 minutes and centrifuge. Label the tube with the patient’s name, ID number, specimen type, and date collected. Store refrigerated at 4ºC or frozen, and ship on refrigerant gel packs or dry ice.

What is a venipuncture vacuum collection system?

Exercise 2: Venipuncture Vacuum Collection System14 Vacuum Blood Collection System The vacuum system consists of a double-pointed needle, a plastic holder or adapter, and a series of vacuum tubes with rubber stoppers of various colors, the colors indicate the type of additive present.

What is specimen collection and processing in blood science?

Blood Specimen Collection and Processing. The first step in acquiring a quality lab test result for any patient is the specimen collection procedure. The venipuncture procedure is complex, requiring both knowledge and skill to perform.
