Factors Leading to Blood Sample Cancellation: Poor Patient Preparation, Incorrect Labeling, and Improper Collection Techniques

Summary:

• Poor patient preparation
• Incorrect labeling or documentation
• Improper sample collection techniques

Poor Patient Preparation

One of the leading factors that can lead to the cancellation of a blood sample by the phlebotomist is poor patient preparation. Proper patient preparation is essential to ensure accurate and reliable blood sample collection. Failure to follow the necessary preparation steps can result in the sample being contaminated or compromised, leading to the cancellation of the sample.

Factors contributing to poor patient preparation include:

1. Fasting requirements not met: Some blood tests require the patient to fast for a certain period before the sample is collected. Failure to adhere to these Fasting requirements can result in inaccurate Test Results and lead to the cancellation of the sample.
2. Improper hydration: Dehydration can affect the composition of the blood, leading to inaccurate Test Results. It is essential for patients to be adequately hydrated before a blood sample is collected.
3. Medication interference: Certain medications can affect the results of blood tests. Patients should disclose all medications they are taking to the phlebotomist to ensure accurate sample collection.

Incorrect Labeling or Documentation

Another common reason for the cancellation of a blood sample by the phlebotomist is incorrect labeling or documentation. Proper labeling and documentation are critical to ensure the integrity of the sample and prevent mix-ups or errors in the testing process. Failure to accurately label or document a blood sample can result in the sample being rejected and the need for a redraw.

Common errors in labeling or documentation include:

1. Missing information: Failure to include essential information such as patient name, date and time of collection, and test ordered can lead to the cancellation of the sample.
2. Incorrect labeling: Mislabeling a sample with the wrong patient information or test can result in serious consequences and requires the cancellation of the sample.
3. Illegible handwriting: Poor handwriting can lead to confusion and errors in the testing process. It is essential for all labels and documentation to be written clearly and legibly to prevent cancellation of the sample.

Improper Sample Collection Techniques

Lastly, improper sample collection techniques can also lead to the cancellation of a blood sample by the phlebotomist. Proper technique is essential to ensure the safety of the patient and the accuracy of the sample. Failure to follow proper collection techniques can result in contaminated or compromised samples, leading to the need for a redraw.

Common errors in sample collection techniques include:

1. Contamination: Failure to properly clean the collection site or handle the sample can result in contamination and the cancellation of the sample.
2. Incorrect order of draw: Using the incorrect order of draw when collecting multiple tubes of blood can result in Cross-Contamination and lead to the cancellation of the sample.
3. Insufficient sample volume: Not collecting enough blood for the required tests can result in the cancellation of the sample and the need for a redraw.

In conclusion, there are several factors that can lead to the cancellation of a blood sample by the phlebotomist in the United States. Poor patient preparation, incorrect labeling or documentation, and improper sample collection techniques are common reasons for sample cancellations. It is essential for phlebotomists to follow proper procedures and techniques to ensure the integrity and accuracy of blood samples collected from patients.
