Q: do healthy individuals have some (within normal range as per laboratory) beta 2 microglobulin in their blood?or is any value, even if w/in range, bad? normal range per lab is <2.52 and my value was 1.74.

That’s fine. : The absolute presence or absence of a substance in the body is not what defines normality. As long as you’re result is within the range that the laboratory defined as normal, then that result is normal, and not suggestive in and of itself of any pathologic process.

Q: does dehydration give wrong a laboratory test of blood chemistry?

No: Dehydration will lead to a change in laboratory values on blood tests but they are still accurate. Once the dehydration is treated, the other values will change accordingly.

Q: on laboratory blood tests, which ones look for anemia?

CBC: Complete blood cell count includes measurement of hemoglobin and red cell count.

Q: my baby at birth had contingent hypothyroid. we had taken few blood samples at different laboratories for the results. my concern is whether any limit in volume of blood samples which can be taken per week or in a month?

minimal amount: TSH testing requires a small amount of blood and even getting tested every week will not cause harm. It is imperative to ascertain the thyroid function of the child as this hormone is related to brain development. Wish you and your child good health!

Q: i got my blood glucose checked in laboratory after 13 hour fasting. the result is " plasma glucose fasting =82mg/dl". is to take reading aftet13h is fine?do i need to check random also? my age 30 and healthy.or its fine?

Valid number: A young, healthy adult can do his fasting blood sugar screening test at 10, 11, 12, or 13 hours after last eating or drinking anything with calories, and his test result should be valid. We don't do random (we just do fasting) blood glucose screening tests on normal, healthy adults.

Q: had aids test. that blood was dropped off down on the basement floor in laboratory. so how long can hiv alive?

A while: Hiv can survive in cells within blood unless the blood has dried or been treated with a substance that will kill the virus. If you were exposed by hiv+ blood coming in contact with an area of damaged skin, or into your eyes, then there is a risk, although small, that you could get this. Most labs have protocols for prophylactic anti-retroviral therapy for personnel who have been exposed.

Q: i am going to check my lipid profile test. laboratory says it requires 12hours fasting.can i perform blood sugar level test with same sample of 12h fasting or i was reading on net 8 hours of fasting is required for glucose level test or must be 8h?

Same sample: The same 12-hour fasting sample works for Lipid Profile testing and Fasting Blood Glucose testing. Usually, a 10-hour fast is adequate for either test but a patient should follow his doctor's or the lab's instructions.

Q: where in the usa theres a direct-to consumer laboratory testing (blood test) facility where someone can get tested for antibody panels related to limbic encephalitis?

: A number of auto-immune encephalitides have been described and many are triggered by viral issues. Limbic encephalitis describes a specific focal location. This is a complex area, best reserved for specialized neurologists, or infectious disease specialists, and hospitalists most commonly see these cases. This is NOT a "direct-to-consumer" area.

Question 1

my chromogranin a blood test shows high 21.00 , according the lab, what does that mean?

Accepted Answer

Chromogranin A: http://emedicine.medscape.com/article/2114314-overview

due to margin of error, i would discuss this result with the ordering doctor.  They may have low or high index of suspicion depending on your symptoms, exam and other lab tests.

Question 2

why my blood pressure is always high but during allthe laboratories all the results are normal. should i medicate with maintenace?

Accepted Answer

Labs Rarely Help: Unfortunately, it's very rare that a laboratory study can explain the cause of hypertension (high blood pressure). The vast majority of cases are what we call "primary" hypertension, which is a simple way to say "we don't really know why." most people should start with restriction of salt in their diet. If your resting blood pressure is still >140mmhg (top number, systolic), meds are advised.
