For the following questions, select the one best answer. Which one of the following would be considered a preexamination/preanalytical error?

A) reporting a critical lab value on the wrong patient
B) testing the wrong aliquot for a glucose test
C) underfilling the aliquot container
D) changing a result without documenting it
A blood type can be defined as a classification of blood that is based on the antigenic substances present or absent on the surface of RBCs (red blood cells). These antigens can be classified under proteins, carbohydrates, glycoproteins, or glycolipids. Blood types are inherited. The most common type of blood groups is ABO blood group and Rh group.
DTC genetic testing is a hustle free method where the client can directly purchase the kit and get his medical check-up done without involving any doctor or a third party. The client will collect his sample by himself by swabbing the cheek cells, and the samples can be sent to a laboratory for DNA (deoxyribonucleic acid) test analysis.
Hence, the options a, b and d are incorrect.
Aliquot or sample acts as the whole of representation. Underfilling the container of aliquot is regarded as one of the preanalytical and preexamination error. A blood sample is taken from the cord following the delivery of the baby.

D) blood gases
Porphyrins are the group of heterocyclic organic compounds. These are the macrocycle that are composed of four subunits of pyrrole that are interconnected at the carbon atoms by the methane bridges.
Agglutination is a biological process of clumping of particles. It occurs when an antigen is mixed with its corresponding antibody. This method is commonly used for blood grouping. In this process, anti-A, anti-B and anti-Rh antibodies are separately mixed with the blood sample and the agglutination or the clumping of the blood is observed.
Cholesterol is the extra fat stored in the body in the form of sterol. High cholesterol marks the obesity like health problems. Melatonin cannot be used for the treatment of high cholesterol in patients.
Hence, the options a, b and c are incorrect.
ABG is a sampling of blood for arterial blood gases. The test is a useful tool to determine treatment in critically ill patients with blood related dysfunction in respiratory, metabolic or renal systems. The test helps to determine the exchange levels of gases in the blood.
