NEW QUESTION 208
Overcentrifugation may cause either a false negative result (if too much agitation is required for resuspension), or a false positive, (if centrifuged clumps cannot be completely dispersed). High concentration of IgG paraprotein, and failure to adequately wash cells can leave unbound IgG which will neutralize antiglobulin reagent. Delay of addition of antiglobulin reagent may allow previously bound IgG antibody to dissociate from red cells.

NEW QUESTION 214
Type I hyperlipoproteinemia is a form of hyperlipoproteinemia associated with deficiencies of lipoprotein lipase. Hyperlipoproteinemia type II is the most common form and is classified into type IIa and type IIb, depending on whether there is elevation in the triglyceride level in addition to LDL cholesterol.
Hyperlipoproteinemia type III is associated with high chylomicrons and IDL. Hyperlipoproteinemia type IV is assoicated with high triglycerides. It is also known as hypertriglyceridemia. Hyperlipoproteinemia type V is similar to type I, but with high VLDL in addition to chylomicrons.
An obese adult with premature arteriosclerosis is seen in the clinic. When her serum is tested no chylomicrons are present, LDL are normal and VLDL are increased. There is an increase in triglycerides and slight increase in cholesterol. Lipoprotein electrophoresis reveals a heavy pre-beta band. She has no skin rash and uric acid is increased. This patient has a hyperlipoproteinemia with the MOST likely type of:

NEW QUESTION 217
The correct response is option B: The Hepatitis B “e” Antigen (HBeAg). This antigen indicates the virus is actively replicating and therefore the patient is very infectious. The hepatitis B “e” antigen is present when the virus is actively replicating. In cases of unintentional needlesticks, infectivity is of highest concern. The risk for infection is greatest during phases of increased HBeAg serology. The Hepatitis B surface antigen is the first detectable marker, but if the patient is known to have Hepatitis B already, it would be relatively unhelpful to confirm the condition with another HBsAG test. The core antigen is not detectable because it is covered by the nuclear envelope. Antibody response patterns would not be very helpful either as the patient has already been diagnosed with acute Hepatitis B. IgG antibodies would indicate recovery, which is not the case for this patient and IgM antibodies indicating a recent or acute infection would only confirm what is already known.
Recall, in cases of unintentional needlesticks, infectivity is of highest concern.
A phlebotomist at a local hospital recently had an accidental needle stick while drawing blood from a patient being treated for acute hepatitis B. Which serological marker from the patient would be of most value to the physician evaluating the phlebotomist’s possible infection status?

NEW QUESTION 221
The indole (modified Kovacs’ reagent) is used to assess the ability of certain bacteria to produce indole by the deamination of tryptophan. Indole reacts with aldehyde in the Kovac’s reagent to produce a red color. An alcoholic layer holds the red color as a ring at the top of the tube used for the idole test.
If a bacteria produces the enzyme tryptophanase to break down the amino acid tryptophan, which of the following tests will be positive with Kovac’s reagent?

NEW QUESTION 230
n reporting out Gram stains, one should not go beyond what objective observation will allow. In this case, bacterial cells are observed, which are spherical and gram-positive. Their arrangement in tetrads and clusters might be helpful to the physician, suggesting staphylococci. However, one should stop short of naming staphylococci in an official report, as the large gram-positive cocci in tetrads is also suggestive of Micrococcus species, for which human infections have not been reported.
A Gram stain of the serous exudate is shown in the image. The appropriate report would read:
