What does low t1 signal intensity mean?
I just had an MRI done and one of the comments was that an area of the scan showed a low signal intensity...as in, something is wrong with the tissue.

What blood types are possible from an B positive and A positive parent?
It depends what the second gene for each parent is. Bx+ and Ax+ is the information given.
The x could be B for Bx and A for Ax. The x could also be O for both. So AA and BB or AO and BO.
In all cases the cross between AA and BB would produce AB.
For the cross between AO and BO, the result would be AB, BO, AO, and OO in a 1:1:1:1 ratio.
If the cross is AA and BO, the result would be AB and AO in a 1:1 ratio.
If the cross is BB and AO the result would be AB and BO in a 1:1 ratio.
In all cases the Rh factor would be +
How many watts does a microscope use?
A microscope is nothing more than magnifying lenses. Some of them use artificial light using electricity.
Some microsopes use no electricity (zero watts) while a large electron microscope could use kilowatts.
Why is it important to run a PT and PTT on any sample for a thrombophilia workup?
There are two ways (pathways) that the blood clots. One is the intrinsic and the other is the extrinsic. There are clotting factors (about 13) that are unique to both pathways. The PT measures one pathway while the PTT measures the other. There are also factors that both pathways share or have in common. By testing both the PT and PTT, you are esentially testing for all the clotting factors collectively without ruling out a specific factor which is very expensive to test. Now, these are usually performed prior to a surgery in order to let the surgeons know if there is a bleeding risk to the patient. This process doesn't include other factors that have to do with the clotting process like platelets counts, platelet aggregation tests (bleeding time), or biochemical imbalances like calcium deficiencys.
Can chicken liver really change blood type A to type O?
No, chicken liver cannot change blood type. Blood type is determined by genetic inheritance and is not affected by the consumption of specific foods. Changing blood type is not possible through dietary means.
An MPV stands for "multi-person vehicle" and is the name given to people carriers.
Why would c-reative protein be high?
C-reactive protein is high when your body has a high level of inflammation. The test is used to help diagnose autoimmune diseases such as rheumatoid arthritis, lupus and other similar conditions.

What type of rays are used to photograph your bones?
x-rays or RMN (radiomagnetic) RMN are more safe and more aqurate
No, if the male was O pos, the female was O neg, and the baby was O pos, then the mother might need a Rhogam shot. A rhogam shot prevents a "neg" mom from developing antibodies to her "pos" baby which could cause a miscarriage. It's really no big deal, just a little shot.
What could cause a high BUN result?
Kidney's are not working properly, to much protein entering the body, gastrointestinal bleeds, Addison's disease, antibiotics causing false high values.

How do you use omni extra strength soft gel to pass a drug test?
The best explanation would to follow the directions on the back of the box. Omni is normally vary good about posting the best method of taking them in order to pass. As a fellow user, and have never failed when using Omni, normally there are a few steps. 1) Avoid food for atleast 3 hours prior to the screening. 2) You are going to want to drink plenty of water before taking the pill (I'd say 16oz is plenty). 3) After taking the pill drink atleast 48oz. of water. The more you drink, the more you can rest assured. 4) Urinate as frequently as possible. The safest bet is to urinate atleast 3 to 4 times before leaving to assure your system is flushed. P.S. The Omni product does not clean your system, but rather mask it. The usual effectiveness is usually between 1 to 2 hours after you take it and will last between 2 to 4 hours. So after you find out about the test, I'd suggest you not smoke. With the pill, don't worry about performing any outstanding tasks (i.e. drinking elevated amounts of water prior to the day of taking the pill). I'd suggest taking the pill 2 hours before the test, therefore you've assured its readiness and know it will last up to 4 hours after test. Remember, drink roughly 12-16oz prior and 48oz minimal after taking it. Urinate frequently to flush out toxins and you're in the clear. Enjoy.
How do you introduce a new employee to others in a letter?
The best way to introduce a new employee is with an upbeat tone. You want to highlight their accomplishments, and what they can bring to the organization.
What laboratory test grows a colony of bacteria removed from an infected site?
Culture and sensitivity test
What does a rheumatoid factor of 189 mean?
A rheumatoid factor (RF) blood test measures the amount of the RF antibody present in the blood.
The results of the rheumatoid factor (RF) test may be reported in titers or units:
- A titer is a measure of how much the blood sample can be diluted before RF can no longer be detected. A titer of 1 to 20 (1:20) means that RF can be detected when 1 part of the blood sample is diluted by up to 20 parts of a salt solution (saline). A larger second number means there is more RF in the blood. So a titer of 1 to 80 shows more RF in the blood than a titer of 1 to 20.
- Nephelometry units show how much light is blocked by the blood sample in the tube. A high level of RF causes the sample to be cloudy, so less light passes through the tube than when the RF level is low. So an RF level of 100 units is higher than one of 40 units.
The normal values listed here-called a reference range-are just a guide. These ranges vary from lab to lab, and your lab may have a different range for what's normal. Your lab report should contain the range your lab uses. Also, your doctor will evaluate your results based on your health and other factors. This means that a value that falls outside the normal values listed here may still be normal for you or your lab.
You can usually get the results within 24 hours.Rheumatoid factor (RF)Titers
Less than 1:80Units
Less than 60 units per milliliter (U/mL)
Check with your doctor to see what the normal range is for the lab that tested your blood.
High valuesHigh RF levels may be caused by:
- Rheumatoid arthritis. This is the most common reason for a positive rheumatoid factor (RF) level.
- Hepatitis C infection.
- Other autoimmune diseases, such as systemic lupus erythematosus (SLE), scleroderma, Sjögren's syndrome, and vasculitis.
- Infectious diseases, such as tuberculosis, mononucleosis, syphilis, and malaria.
- Liver diseases, such as cirrhosis and chronic active hepatitis.
- Infection of the heart (endocarditis).
- Leukemia.
To centrifuge a red tube you will have to run the blood through and then put it back into the body. The red tube is used to collect plasma.
What would cause blood not to flow out when nurse tries to draw blood?
She could be missing the vein or be agains a valve in the vein
What are some disadvantages and advantages of DNA microarray tests?
Disadvantages include incomplete coverage, which can lead to false normal results, and the ability to test only for unbalanced rearrangements (duplications and deletions), and not balanced translocations or inversions.
However being high throughput and cost effective are the most elements for this technology, it still suffers lack of perfect processing methods and acceptable sensitivity as much as real time PCR
What determines what blood group can be given to what blood group?
Blood group compatibility is determined by the presence of specific antigens on red blood cells. For example, people with blood type O are universal donors because they do not have A or B antigens. In contrast, people with blood type AB are universal recipients because they do not have antibodies against A or B antigens. Matching blood types helps prevent adverse immune reactions in transfusion recipients.
What is the differnce between active and passive transport?
passive doesn't neeed energy but active transport does
Why anti A of O group not reacting with antigen A of A blood group?
In the ABO blood group system, individuals with blood type O do not have the A or B antigens on their red blood cells. Therefore, there is nothing for the anti-A antibodies in the plasma of an O blood type individual to react with when encountering blood from an individual with blood type A. As a result, there is no agglutination or clumping reaction between anti-A antibodies and A antigen on red blood cells, making it safe to transfuse blood between these blood types.
Can chemicals in detox shampoo be detected in a hair follicle test?
Any shampoo that would be effective enough to fool a drug test would definitely be detectable. There aren't any, though, so it doesn't really matter. The issue is that the drug residues that are being tested for aren't on the hair where they can be washed off, they're in the hair. A shampoo that could get them out would have to damage the hair so severely that the person doing the testing would look at the clumps of ash that you were trying to pass off as "hair" and immediately know something was up.
What is cost of carotid Doppler test?
It would depend on where you live and the facility performing the test. Complete exam charges to insurance average about $800-$1200 with the facility payment range about $180-$400. These numbers are from the Pittsburgh Pa region. Screening or limited exams not billed to insurance would range from $35-$95. You can always call your local hospital and they will tell you their charges. Also let them know if you are unable to afford a procedure and they may help you. good luck.
