Microcontainer collection order of draw differs from regular peripheral blood collection order of draw. When performing a capillary draw, the lavender top container is obtained first. This decreases the possibility of clots in the container which would invalidate the results of the complete blood count test.

After the lavender is drawn, other containers with anticoagulants would be collected, and containers without anticoagulants would be collected last.

A phlebotomist must perform a skin puncture to obtain capillary specimens for a complete blood count (CBC), a plasma-based chemistry test, and a serum-based immunology test. The microcollection containers that will be used are lavender top containing EDTA anticoagulant, green top containing heparin anticoagulant, and gold top containing no anticoagulant. Which microcollection container should be collected first?

A. Lavender top

B. Green top

C. Gold top

D. The order of draw is not important.

HbsAg is positive in acute and chronic Hepatitis B infections, since the antigen is found on the actual surface of the virus. HbeAg is present in the blood when the hepatitis B viruses are replicating, indicating an active infection. Anti-Hbc IgM is present due to the immune response to the presence of the hepatitis core antigen and indicates an acute infection. Anti-HBs is generally interpreted as indicating recovery and immunity from hepatitis B virus infection, according to the CDC. Given the following results, what is the immune status of the patient? HbsAg: positive HbeAg: positive Anti-HBc IgM: positive Anti-HBs: negative

A. acute infection

B. chronic infection

C. immunization

D. susceptible
