21
Q

Bilirubin crystal appearance

A

Fine needles forming clusters

22
Q

Leucine crystal appearance

A

Spheres with concentric circles or striation

23
Q

Tyrosine crystal appearance

A

Fine, delicate needles in clusters or sheaves

24
Q

Cholesterol crystal appearance

A

Flat, rectangular plates with notched corners

25
Q

Cystine crystal appearance

A

hexagonal plates

26
Q

What is the purpose of the color compensation field on the strips?

A

The color compensation pad assesses urine color and modifies the test results by subtracting the urine color from the color change obtained on the test reaction pads

27
Q

What pigment gives urine its yellow color?

A

urochrome

28
Q

What are the critical values?

A

4+ glucose, 3+ ketones, positive legionella

29
Q

Does a negative nitrite rule out a UTI?

A

No, bacteria may not reduce nitrates, may not have sat in bladder long enough, ascorbic acid may be interfering, and patient may not eat enough nitrates

30
Q

Does a negative legionella antigen test rule out legionella?

A

No, it only detects legionella sero group 1

31
Q

Why does an increase of Gardnerella indicate bacterial vaginosis?

A

In a bacterial vaginosis infection, the lactobacillus population decreases, so the environment is not as acidic, allowing overgrowth of Gardnerella and other anaerobic bacteria

32
Q

Why must a positive leuko on a one year old baby be marked as an unconfirmed positive?

A

False positives can occur in breast fed babies

33
Q

Round refractile globules with perfect maltese crosses

A

Oval fat bodies

34
Q

An antibiotic would be most effective in an acidic pH, should eat more

A

protein

35
Q

Colorless, clear, hexagonal crystals infer what condition?

A

Cystinosis

36
Q

Elevated urobilinogen and negative bilirubin indicate

A

Hemolytic disease of the newborn

37
Q

Method of choice for SG in patient with x-ray contrast dye?

A

Reagent strip

38
Q

Multiple myeloma with 3+ protein with large amount of Bence Jones proteins

A

Prerenal proteinuria

39
Q

ketone body that doesn’t appear in urine
