Question 1

how accurate is the blood test for distinguishing between type one and type two herpes?

Accepted Answer

Type specific = good: Type specific herpes tests are great at distinguishing between type 1 & 2. Rarely if someone is highly positive for type 1 w/ a very low positive for type 2, we believe it could be a false positive, even with type specific tests, which are the best tests out there to screen for herpes. If u have a genital sore, immediately see a doc for a swab which reliably distinguishes type 1&2, if positive.

Question 2

can you tell me about hiv aids blood test two or three years just one time after infection the result can be true or false. please help how shoul i do for accurate?

Accepted Answer

See details: If you tested negative after 2-3 years then you are negative and do not have the virus.

Question 3

24 weeks 2 days pregnant. failed 1hr test with a result of 9mmol/165mg. i have the next blood test in two weeks. i bought diabetic urine tests , if my sugar is truly this high will it accurately pick up in my urine?

Accepted Answer

Urine tests accuracy: "Diabetic urine tests" are no longer recommended for pregnant diabetics. They may not reflect accurately the levels of sugar in your blood. You will need a glucometer. If you have been diagnosed with gestational diabetes, it would be best to consult a "diabetes nutritionist" and a MFM team, i.e. a group of materno-feto-medicine clinicians who have expertise in managing pregnant diabetics.

Question 4

hcg blood test, a lab urine test and two home test came back negative for pregnancy. it had been 22 days since intercourse (only precum from broken condom), and 6 days after missed period. how accurate is it?

Accepted Answer

: You are asking a technical lab question about a particular lab test. That question is best answered by the producer of the test. In general, most home pregnancy tests are very accurate, more than 95%, 22 days after sexual contact

Question 5

could i have an ectopic pregnancy with hcg level too low for home pregnancy test even after 2 months? missed two periods, tested 6x negative. had blood test 3 week after first missed period, negative? would that blood test be accurate, or too soon ?

Accepted Answer

: Irregular menstrual periods are common. The fluctuations of estrogen and progesterone can be easily affected by stress, weight gain/loss, exercise, lack of sleep, thyroid problems, and uterine issues. If your period irregularities persist, talk to your Dr about what testing can be done to determine the cause. You are not pregnant, as tests at those dates are very sensitive.

Question 6

are blood test more accurate than clear blue?

Accepted Answer

Blood Test vs Urine: It would be better to say that the blood test is able to detect smaller amounts of the hCG that indicates pregnancy.  Urine home pregnancy tests are very accurate and also very sensitive, and they vary a bit brand to brand.    Once you have missed your period, either test would normally detect hCG these days.  Good luck!

Question 7

what is the most accurate blood test to check  b-12 levels?

Accepted Answer

Serum tests: B12 levels can be testing in the blood directly but I also order a methylmalonic acid level if I have high clinical concern.  This is elevated prior to B12 levels being low (could be normal range).  B12 is the cofactor for the enzymatic reaction involving methylmalonic acid so without B12 the MMA levels increase.  Then issue is why is one deficient in Vit B12?

Question 8

how accurate isa blood test?are at home tests just as accurate?

Accepted Answer

Depends: Lab tests need be evaluated in term of sensitivity, specificity and predictive value. Some of these parameters depend on the population being tested. Home tests are generally accurate, provided the testing is performed strictly according to the instructions of the manufacturer. Home tests are generally screening tests and often require confirmation with a test in an accredited laboratory.

Question 9

two negative oraquicks and a negative 4th generation blood test after risk event 4 months ago should i take another or be worry free ?

Accepted Answer

Not HIV positive: You should already be worry free. But, if you aren't then test again. You are not HIV positive.

Question 10

Accepted Answer

Unclear question: Fasting plasma glucose, done at two differnt times, glucose tolerance test, and A1c results can all be used to diagnose diabetes and if done properly, are accurate.
