The conidia of Exophiala species are produced within phialides that extrude the conidia in tight, ball-like clusters.

The large, drum stick-shaped muriform macroconidia of Alternaria species are arranged in short chains; the small, elliptical conidia of Cladosporium species are arranged in both long and short, branching chains.

Which of the following dematiaceous fungal species produce conidia in clusters?

This type of laboratory professional is responsible for the technical aspects of managing the operation of the laboratory and is most likely an MLS with additional education in administration:

The color coding of evacuated tubes provides information about all of the following except the: Question options:

In healthy individuals, procalcitonin is only synthesized by the thyroid C cells. In bacterial infections, PCT is synthesized in various extrathyroidal neuroendocrine tissues.

In healthy individuals, procalcitonin is synthesized by which cells in the body?

A zone of inhibition is the area around an antibiotic-infused paper disk that does not show any bacterial growth. The antibiotic impregnated on the disk will diffuse into the agar in the area surrounding the disk. If the bacteria are sensitive to the antibiotic, they cannot grow near the disk. The size of the zone is proportional to how sensitive the organism is. If the organism is resistant to the antibiotic, it will grow very closely to the disk.

The size of the zone of suppressed growth on a sensitivity plate using sensitivity disks is referred to as the zone of:

Eosinophils do not have cytoplasm containing large purple/blue-staining granules. Instead, their granules are large but are orange/red in color. These granules are very distinctive for this type of cell, typically making their identification simple.

ll of the following statements describe an eosinophil EXCEPT:

AABB Standards do not require a DAT, autologous control, or a minor crossmatch for pretransfusion testing.

Essential components of compatibility testing include all of the following except :

Mrs. Jones, a diabetic, is admitted to the hospital on November 25th. It appears that she has had an AMI but did not feel the severe chest pain because of diabetic neuropathy. She has not felt well since November 20th and her physician believes she possibly had an AMI on November 20th.

Assuming that the infarct was uncomplicated, which of the following cardiac biomarkers would most likely still be elevated and would assist in an AMI diagnosis?

The correct set of patient data would be: Hgb A = 60%, Hgb S = 38%, Hgb A2 = 2%, Hgb F = 0%

Patients with sickle cell trait commonly have Hgb A values between 40 and 60%, Hgb S values between 20 and 40% and Hgb A2 values between 2 and 3%.

A known sickle cell trait patient has a hemoglobin electrophoresis test performed. Which of the following hemoglobin percentage sets would most closely match this patient's diagnostic state?

Serological diagnosis of active or recent infection generally requires the demonstration of IgM antibody, or the demonstration of a fourfold rise in the titer of specific IgG antibody.

Which of the following would be considered most significant as it relates to serological testing:

Immunology

The immunoglobulin molecule is made up of both heavy and light chains - the light chains can be comprised of which of the following:

Creatinine clearance tests are utilized to estimate the glomerular function of the kidney. The creatitine clearance calculation is defined as the volume of plasma that is cleared of creatinine by the kidney per unit of time and uses the following formula:

creatinine clearance = Urine creatinine conc x Volume / Plamsa creatinine conc

Creatinine clearance measurements have a recommended specimen requirement = 24-hour urine collection.

Which of the following tests would be useful in the assessment of glomerular filtration:

Match each of the descriptions with the appropriate magnification:

1. Color, Rouleau, Overall Slide Quality, Cell Distribution

2. Platelet estimates RBC-platelet-WBC morphology WBC differential RBC inclusions

3. Select area to examine, WBC estimate

Either immunofixation or immunoelectrophoresis can be used to confirm Bence-Jones proteinuria.

Which of the following methods would be used to confirm the presence of Bence-Jones protein in the urine:

The cells indicated by the arrows in the image are spherocytes. Spherocytes have a decreased surface to volume ratio and are therefore smaller with an increased MCHC. Spherocytes have lost their bi-concave shape and are spherical in shape, hence the name.

What are the cells that are indicated by the arrows in this peripheral blood smear image?
