What are the consequence for blood specimen collection when a vacuum tube takes a very long time to fill?
If a vacuum tube takes a very long time to fill during blood specimen collection, it can lead to hemoconcentration where the blood cells become concentrated due to prolonged contact with the tube walls. This can affect the accuracy of test results as the proportion of blood cells to plasma may be altered. Additionally, prolonged exposure to air can cause changes in blood composition and potentially lead to inaccurate test results.

What is specimen collection?
Specimen collection is the process of obtaining samples from a person, animal, or environment for further analysis or testing. This can involve various methods such as blood draws, swabs, urine samples, or tissue biopsies, depending on the specific type of specimen needed for diagnostic or research purposes. Proper collection techniques are essential to ensure accurate results and avoid contamination.
What the common anticoagulant used in the vacuum tube?
The most common anticoagulant used in vacuum tubes for blood collection is ethylenediaminetetraacetic acid (EDTA). It is effective in preserving blood samples by binding to calcium ions, preventing coagulation.
What color blood drawing tube is used to collect a serum specimen?
A red-colored blood drawing tube is typically used to collect a serum specimen.
What electrolyte test results is affected by hemolyzed blood specimen?
Potassium levels can be falsely elevated in a hemolyzed blood specimen due to the release of intracellular potassium from damaged red blood cells. It is important to request a redraw if a specimen appears hemolyzed to ensure accurate electrolyte results.
A cbc specimen rejected for testing by the hematology dept the tube was filled completely and labeled properly what might have been the reason for rejection?
The specimen may have been clotted, hemolyzed, or not properly mixed. It could also have been expired or contaminated. It's important to follow proper blood collection procedures to ensure accurate test results.

Hemolysis of a blood specimen is caused bycompletion?
Hemolysis of a capillary specimen can be caused by intense squeezing of the skin. It can also be caused by the scraping of blood at the surface of the skin. If this occurs, adding warmth will ensure sufficient blood collection.
What is the vacutainer?
A vacutainer is a vacuum pressured flask that is normally used for blood collection. Useful for drawing blood.
How can hemolysis of a capillary specimen can be caused?

Which combination system can be used with syringe and the vacuum tube?
A needle holder or adapter can be used as a combination system with both a syringe and a vacuum tube. This allows for easy transfer of blood samples between the syringe and the vacuum tube during blood collection procedures.
Iatrogenic anemia is a condition in which?
The patient has become anemic from too much and too many blood draws for specimen collection
When the doc says the blood and pus in the urine specimen can be caused by collection what does he mean?
If a urine specimen isn't a clean-catch, mid-stream urine, it's possible for external blood or white blood cells to contaminate the sample, given the mistaken impression that there's urinary disease.
What is single specimen collection?
Single specimen collection refers to the process of obtaining and storing a single sample (such as blood, urine, tissue, etc.) from an individual for diagnostic or research purposes. This single sample is typically used to analyze specific markers or characteristics of the individual's health status or condition.
What the common anticoagulant used in the vacuum tube?
The most common anticoagulant used in vacuum tubes for blood collection is ethylenediaminetetraacetic acid (EDTA). It is effective in preserving blood samples by binding to calcium ions, preventing coagulation.
What can be done prior to the skin puncture to aid in obtaining the specimen?
Using gravity to increase blood collection is one strategy to aid in getting a puncture specimen. Using a warm compress will also increase blood flow. Milking the digit vigorously should be avoided, as it can affect results.
What blood collection tube is sodium fluoride in?
Sodium fluoride is typically found in gray-top blood collection tubes, which are used for glucose testing because sodium fluoride acts as a glycolysis inhibitor to preserve the specimen for accurate glucose measurements.
What type of specimen is required for most blood tests?
For most of the blood tests fasting blood specimen is required
