Micro UA pt 3

Question 1

Urinary crystals

Answer 1

formed by precipitate of urine solutes

crystal formations:

lower temp = greater precipitation

inc concentration the ability to remain in solution decreases

PH IMPORTANT

Question 2

Abnormal Crystals

Answer 2

liver disease/inborn errors of metabolism

met. renal disease, renal calculi

Question 3

ID of crystals

Answer 3

morphology
pH
polarized light/ability to polarize
solubility

Insoluble = stays in crystal formation

Soluble= dissolves

Question 4

Soluble Crystals

Answer 4

dissolves

amorph urates are soluble in NaOH alkalone also by heat

Question 5

normal crystals

Answer 5

normal relative to concentration of crystals and health status

Question 6

Amorphous

Answer 6

Non-crystaline, no defined shape, dont confuse with granular casts

no clin significance

Question 7

Amorphous urates

Answer 7

acidic urine, normal, sediment is pink (Ca,mg,na,k)

brown/yellow/pink gran

occur due to refridgeration
soluble in heat/alkaline

Question 8

Amorphous Phosphates

Answer 8

Alkaline urine

phophs/calcium

sediment is white

soluble in acetic acid

Question 9

Sodium urates

Answer 9

protein rich diet, not reported
due to fridge

Question 10

uric acid crystals

Answer 10

acidic urine

normal in low concentrations

inc amounts/inc purines and nucelic acids
