Q:l Thel laboratorianl completedl thel mixingl studyl orderedl forl Johnl Doe.l Thel resultsl
arel asl follows:
Initiall aPTTl result:l 167l seconds
Initiall 1:1l Mixl withl Normall Pooledl Plasma:l 158l seconds Incubatedl 1:1l Mixl withl Normall Pooledl Plasma:l 150l seconds
Whichl ofl thel choicesl belowl wouldl mostl likelyl explainl thel resultsl forl thisl patient?
A.l Factorl VIIIl deficiency B.l Immediate-actingl coagulationl inhibitor C.l Time/temperature-dependentl coagulationl inhibitor D.l Factorl VIIl deficiency
Answer:
B; Thisl patientl isl mostl likelyl sufferingl froml anl immediate-actingl coagulationl inhibitor;l mostl commonly,l lupusl anticoagulant.l Noticel thatl thel additionl ofl normall pooledl plasmal doesl notl correctl uponl initiall orl incubatedl mix,l whichl meansl thatl thel inhibitorl isl notl timel orl temperature-dependent.
Factorl VIIIl isl notl thel correctl answerl asl al factorl deficiencyl wouldl havel correctedl uponl thel additionl ofl normall pooledl plasma.l Factorl VIIl isl notl thel correctl answer,l asl thel aPTTl assayl doesl notl accountl forl factorl VIIl activityl orl concentration.
Q:l Givenl thel followingl results,l whatl isl thel immunel statusl ofl thel patient?
HbsAg:l positive
HbeAg:l positive
Anti-HBcl IgM:l positive
Anti-HBs:l negative
A.l acutel infection B.l chronicl infection C.l immunization D.l susceptible
Answer: 3 / 4
A; HbsAgl isl positivel inl acutel andl chronicl Hepatitisl Bl infections,l sincel thel antigenl isl foundl onl thel actuall surfacel ofl thel virus.l HbeAgl isl presentl inl thel bloodl whenl thel hepatitisl Bl virusesl arel replicating,l indicatingl anl activel infection.l Anti-Hbcl IgMl isl presentl duel tol thel immunel responsel tol thel presencel ofl thel hepatitisl corel antigenl andl indicatesl anl acutel infection.l Anti-HBsl isl generallyl interpretedl asl indicatingl recoveryl andl immunityl froml hepatitisl Bl virusl infection,l accordingl tol thel CDC.

A; Albuminl isl al "negative"l acutel phasel proteinl sincel itl isl foundl inl decreasedl levelsl duringl acutel phasel response.l Alpha-1-antitrypsin,l fibrinogen,l andl ceruloplasminl arel alll "positive"l acutel phasel proteinsl thatl arel foundl inl increasedl levelsl duringl acutel phasel response.
Q:l True/False
Al pregnantl femalel whol receivedl RhIgl atl 28l weeksl gestationl hasl al positivel antibodyl screenl atl delivery.l Ifl thel antibodyl hasl beenl confirmedl asl anti-Dl alonel andl reactsl 1+l inl thel indirectl antiglobulinl testl withl D+l redl cells,l performingl al titrationl tol investigatel ifl thel anti-Dl isl immunel isl goodl practice.
Answer:
False Becausel lowerl titersl couldl bel duel tol bothl passivel andl immunel anti-D,l inl thel absencel ofl resultsl thatl suggestl immunel anti-D,l routinel antibodyl titrationl isl notl al goodl usel ofl timel comparedl tol assumingl thatl anti-Dl isl passive.l
