What procedure do iron tests involve?
Iron tests are performed on samples of the patient's blood, withdrawn from a vein into a vacuum tube. The amount of blood taken is between 6 mL and 10 mL (1/3 of a fluid ounce).
What samples need to be run 15 minutes apon drawing ptt ABG PKU?
For tests such as PTT (Partial Thromboplastin Time), ABG (Arterial Blood Gas), and PKU (Phenylketonuria), it is crucial to run the samples promptly after drawing to ensure accuracy. Specifically, ABG samples should be analyzed within 15 minutes to prevent changes in gas levels due to metabolism. Similarly, PTT samples should be processed quickly to ensure reliable coagulation results, while PKU samples should ideally be analyzed as soon as possible to maintain the stability of the metabolites being measured.
What is icteric index and how can measure icetric index?
The icteric index is a clinical indicator used to assess the degree of jaundice, specifically by measuring bilirubin levels in the blood. It is calculated by taking the ratio of total bilirubin to the direct (conjugated) bilirubin levels, usually expressed as a percentage. To measure the icteric index, blood samples are taken and analyzed using a laboratory assay that quantifies the concentrations of total and direct bilirubin, allowing healthcare providers to evaluate liver function and diagnose potential liver diseases.
When is whole blood necessary for a blood transfusion?
Whole blood is generally used when a person has lost a lot of blood. Such blood loss can be caused by injury or surgical procedures. Whole blood is given to help restore the blood volume, which is essential for maintaining blood pressure.
What is lipemic blood?
Lipemic blood serum refers to a condition where the serum is milky white from its high fat content. Lipemic blood serum refers to a condition where the serum is milky white from its high fat content.

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.
What is lipemic severve?
Do you mean severe? Severe lipemia is the harsh presence of excess fats or lipids in the blood.
Can blood glucose level falsely increased in lipemic serum?
Yes, blood glucose levels can be falsely increased in lipemic serum due to interference in some laboratory methods used to measure glucose levels. Lipemic serum contains high levels of triglycerides or fats, which can affect the accuracy of glucose measurements by some glucose assays. This interference can result in erroneously elevated glucose readings.
Can you detect chlamydia in blood samples?
Chlamydia is typically detected through urine or swab samples, not blood samples. Blood tests are not commonly used for diagnosing chlamydia.
What does lipemic specimen mean?
Containing an unusually high amount of fat. The term has its roots in the "medical" name for fats, lipids. In blood samples, these are identified as having milky serum (the normally clear or yellowish portion of the blood) after being centrifuged. Depending on the tests being done and the methodology used, this can interfere with test results. However, most labs have procedures for working around this problem.
What does specimen slightly hemolyzed mean?
A slightly hemolyzed specimen refers to a blood sample with some degree of red blood cell rupture during collection or processing. This may affect test results and can be caused by rough handling, improper venipuncture technique, or prolonged tourniquet application. It is important to note any hemolysis as it can interfere with certain laboratory tests.
What is the correct sequence when obtaining multiple samples of blood?
The correct sequence when obtaining multiple samples of blood is to collect samples in the following order: blood cultures, non-additive tubes (for serum), tubes with additives (e.g., EDTA, heparin, citrate), and finally, blood samples for coagulation studies. This sequence ensures that samples are not contaminated by additives from other tubes and prevents cross-contamination.
Why would a lab refuse an old blood sample?
A lab may refuse an old blood sample because factors such as degradation of the sample, potential contamination, or changes in test requirements may affect the accuracy and reliability of the results. Using old samples could lead to erroneous or inconclusive findings, compromising the quality of the test outcomes.
What kinds of patient samples are used for the purpose of identifying possible pathogens?
Samples may include stool sample, blood sample, or other samples.
What is a pooled blood product?
A pooled blood product is a collection of multiple donated blood samples in order to test 10 samples at a time to see whether the blood tests positive or negative for certain diseases. If negative, then the cost of testing the other 9 samples has been saved!
