Q: lupus anticoagulant eval. the ref range is <45sec. does the result matter if its over 45? for example, is a result of 51 more indicative of an issue than 46? if the la screen and drvvt screen is high and confirm is - what factors should be checked?

: Pleas touch base with the doctor who ordered the test. Background &amp; context is needed.

Q: can you explain what a positive test for lupus anticoagulant means?

Autoantibodies.: Your body is producing antibodies directed against its own tissues and is likely at increased risk for the development of an autoimmune disease such as lupus erythematosus, rheumatoid arthritis, thyroiditis, vitiligo, infammatory bowel dis or pernicious anemia from gastritis. Lac can cause clotting disorders and miscariages, but is not in and of itself an important predictor of clinical outcomes.

Question 1

hi

i had 2 blood test that came back with lupus anticoagulant in feb 2012. i got told this won't affect me unless i get pregnant again is this true.

Accepted Answer

No: It does increase the risk of pregnancy loss and preterm delivery but can also increase your risk of blood clots and makes estrogen use riskier.

Question 2

can blood work result in a false positive result for lupus anticoagulant factor?

Accepted Answer

No: Positive is positive. However, it is the degree of positivity that is clinically important. Low positive values are generally not clinically important.

Question 3

7 wks 3 days pregnant i got blood tests. protein s, activity is 39. protein c, factor v/viii, prothrombin, b2 glycoproteins, lupus anticoagulant, cardiolipin, antithrombin iii are normal. i have always bled easy and no history of clots. is this bad?

Accepted Answer

: This sounds good overall but the tests you mention are usually done because of clot history rather than bleeding history.  An older test called a “bleeding time” test can help diagnose certain bleeding disorders like Bon Willebrand’s disease which could definitely affect the amount of bleeding after delivery of an infant.

Question 4

my blood has lupus anticoagulant ...i am on blood thinners too ...previously had a clot too 3 years ago.. is there anything i should do as precautions. ..please advise?

Accepted Answer

Carry on: Lupus anticoagulant has a misleading name. Most people who have it don't have lupus, and it is more often associated with excessive clotting than insufficient clotting.  It sounds like you're under a doctor's care now, and for some reason are on long-term anticoagulant therapy.  Only advice: since many drugs have interaction with warfarin, always inform a prescribing doctor that you're taking it.

Question 5

what are rheumatoid factor and other blood test results that suggest lupus?

Accepted Answer

ANA, Sm, antidsDNA: Laboratory tests are important but not the only factor in diagnosing lupus.  Generally the screening test is for anti-nuclear antibodies (ANA) more specific tests are antibodies to sm antigen and double stranded dna.

Question 6

i have many symp. of lupus not limited to fatigue joint pain/swelling rash hair loss doc says my blood test results are fine. do i get a 2nd op? recent test: ana screen,ifa qst-positive ana pattemn qst-nuclear, homogeneous ana titer ost- 1.40 titer?

Accepted Answer

: The diagnosis of lupus requires a combination of clinical findings paired with certain lab values. There is no one lab test that unequivocally clinches the diagnosis. I think it would be worthwhile for you to consult a rheumatologist at the dept of rheumatology at a university hospital near you for evaluation and advice.  If you do,bring records of tests with you.

Question 7

when testing for antiphospolipid antibody syndrome,  does taking baby aspirin affect the lupus anticoagulant (ptt-la, drvvt) test results?

Accepted Answer

It should not: The aspirin inhibits platelets not other parts of the clotting cascade.

Question 8

i had a biopsy on rashes it showed i have lupus. all my blood work is neg (lupus panel) wouldn't it show in blood test? is this diagnosis wrong?

Accepted Answer

Discoid lupus: Have a good talk with the Dr who did the biopsy.

Question 9

lupus anticoagulant eval. the ref range is <45sec. does the result matter if its over 45? for example, is a result of 51 more indicative of an issue than 46? if the la screen and drvvt screen is high and confirm is - what factors should be checked?

Accepted Answer

: Pleas touch base with the doctor who ordered the test. Background &amp; context is needed.

Question 10

can you explain what a positive test for lupus anticoagulant means?

Autoantibodies.: Your body is producing antibodies directed against its own tissues and is likely at increased risk for the development of an autoimmune disease such as lupus erythematosus, rheumatoid arthritis, thyroiditis, vitiligo, infammatory bowel dis or pernicious anemia from gastritis.
