HOESCH TEST (Inverse reaction)

137
Q

Correlations:

Blood: Increased UB
Urine Bilirubin (CB): Negative
Urine urobilinogen: +++

Condition: ??

A

Extravascular hemolytic disease
(Pre-hepatic jaundice)

138
Q

Correlations:

Blood: increased UB/CB
Urine bilirubin (CB): +/-
Urine urobilinogen: ++

Condition: ??

A

Liver damage
(Hepatic Jaundice)

139
Q

Correlations:

Blood: increased CB
Urine bilirubin (CB): +++
Urine urobilinogen: -/decreased (Strip = NORMAL)

Condition: ??

A

Bile duct obstruction
(Post-hepatic or obstructive jaundice)

140
Q

Jaundice due to increased destruction of red blood cells does not produce bilirubinuria

true or false

A

True

  • because the serum bilirubin is in the unconjugated form and the kidneys cannot excrete it.
141
Q

A

Nitrite

142
Q

Q

If the nitrite test area shows a negative reaction, UTI cannot be ruled out

true or false

A

True

  • Some UTIs are caused by gram (+) cocci & yeasts - they lack nitrate reductase enzyme)
