URINALYSIS Flashcards
the amount of filtered plasma
170,000 mL
average daily urine output
1200 - 1500 mL (range of 600 – 2000 mL is considered normal)
The MORE FLUID will intake, urine volume will ____
increase
The LESSER FLUID will intake, urine volume will _____
decrease
the concentration of urine is directly proportional to the ______
specific gravity
“Concentrated Urine”, because urine is “concentrated” the color also affected, it becomes ______.
DARKER
the less concentrated the urine is, the lesser is the _____ of the urine.
color (lighter)
testing of urine with procedures commonly performed in expenditure, reliable, accurate, safe and cost-effective manner.
urinalysis
purpose of urinalysis
- to detect renal disease
- for metabolic screening procedure
- test from asymptomatic beginnings of conditions such as Diabetes Mellitus, Diabetes Insipidus and Liver Diseases
pathways in urine
- glomerulus
- bowman’s capsule
- proximal convoluted
- loop of henle
- distal convoluted tubules
- collecting tubules
- ureter
- urinary bladder
- urethra
renal tubular epithelial cells in nephrotic sundrome, absorb and become engaged with fat known as
OVAL FAT BODIES
indicates lipid droplets contained in the cell
maltese cross
abnormal increase (>2500 ml per 24hrs)
polyuria
polyuria is associated with
diabetes mellitus and diabetes insipidus; or the use of diuretics, caffeine or alcohol which suppress the excretion of ADH.
decrease urine volume (<500 ml per 24hrs) and seen in a state of dehydration
oligouria
oliguria causes
excessive water loss, vomiting, diarrhea, perspiration or severe burns
oliguria is associated with
acute nephritis and shock
- complete suppression of urine formation
- may result from any serious damage to the kidneys or from a decrease in the flow of blood to the kidney
- <100mL/24hrs for 3 consecutive days
anuria
increased urine volume at night
nocturia
involuntary voiding of urine at night
enuresis

- the major organic constituent
- metabolic waste product produced by the liver from the breakdown of protein and amino acids
urea
volume of urea composition
25g/L
major inorganic constituent
chloride
volume of chloride composition
9g/L
Na, K in urine
- lesser amount present
- Na is 4g/L primary from salt, varies by intake
- K is 2g/liter, combined with Cl and other salts
product of creatine metabolism by muscles
creatinine
volume of creatinine in urine
1.5g/L
combines with sodium to buffer the blood
phosphate
volume of phosphate in urine
2g/L
product of nucleic acid breakdown in food and cell
uric acid
