INDIVIDUAL TEST 926
C1 INH Function
Indication
Investigation of angioedema
Method
The analysis is performed on plasma with spectrophotometry.
Result
The result is reported as a percentage of normal human serum and as normal or reduced. Reference interval: 72-129 %.
Interpretation
Results below the lower reference limit may indicate hereditary angioedema (HAE) type 1 or consumption of C1-inhibitor (can be seen in some malignancies). The result should primarily be verified with a new sample as well as to include analysis of concentration of C1-inhibitor and C4.

ENSKILD ANALYS 926
C1-INH funktion
Indikation
Vid utredning av angioödem
Metod
Analysen utförs på plasma med spektrofotometri.
Svar
Resultatet anges som procent av normalt humanserum och som normalt eller sänkt. Referensintervall: 72-129%.
Tolkning
Resultat under nedre referensgränsen kan tyda på hereditärt angioödem (HAE) typ 1 eller konsumtion av C1-inhibitor (kan ses vid vissa maligniteter). Resultatet bör i första hand verifieras med nytt prov för verifiering och även inkludera analys av koncentration av C1-inhibitor och C4.
