This is a blood test that detects the presence of antibodies against smooth muscle.
How the test is performedBlood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.
Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.
Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.
How to prepare for the testNo special preparation is needed.
How the test will feelWhen the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.
Why the test is performedYour doctor may order this test if you have signs of certain diseases (such as hepatitis and cirrhosis) that can trigger the body to form antibodies against smooth muscle.
Normal ValuesNormally, there are no antibodies present.
What abnormal results meanA positive test may be due to:
- Chronic active hepatitis
- Cirrhosis
- Infectious mononucleosis
The test also helps distinguish autoimmune hepatitis from systemic lupus erythematosus.
What the risks areVeins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others. Other risks:
- Excessive bleeding
- Fainting or feeling light-headed
- Hematoma (blood accumulating under the skin)
- Infection (a slight risk any time the skin is broken)
What else can I help you with?
Enzyme antibody hormone and muscle are roles played by?
proteins
Are the kidneys smooth muscles?
No it is not. The liver is a specialized organ involved in protein production, hormone production, detoxification, metabolization of compounds, glycogen storage and digestion. Smooth muscle, on the other hand, makes up a significant portion of the gastrointestinal track. It is interesting to note that a marker for autoimmune hepatitis (a disease of the liver) is called anti-smooth muscle antibody.
What type of muscle is the tricep muscle?
A skeletal muscle.
What connects muscle to muscle and connective tissue to muscle?
Muscle does not connect to muscle. Fascia is a connective tissue that connects muscle to organs. Tendons connect muscle to bone.
How are individual muscle cells different from the muscle tissue in the bicep muscle?
Muscle cells are smaller than muscle tissues.
What type of muscle is associated with type of muscle?
there is a thigh muscle its a skeletal muscle
What binds muscle to bone and muscle to muscle?
Tendons tie muscles to bones and ligaments tie muscle to muscle.
What type of muscle is striated?
Striated muscle tissue is muscle tissue that has repeating tubular muscle cells. Striated muscles include skeletal striated muscle, embryotic branchiomeric muscle, and cardiac muscle.
Whats the difference between muscle mass and muscle hypertrophy?
The difference between muscle mass and muscle hypertrophy is that muscle hypertrophy is the increase in size of skeletal muscle while muscle mass is the weight of your body muscle.
Which type of muscle is the heart made of?
cardiac
What is the name of the muscle that is considered the strongest jaw muscle?
The muscle that is considered the strongest jaw muscle is called the masseter muscle.
Which muscle do you control smooth muscle or skeletal muscle?
You are in direct control of skeletal muscle.
