Why blood for testing is drawn from left ring finger?
I have had multiple blood draws done every year since the middle 1990s and the blood has always been taken from veins in my forearm (sometimes left, sometimes right) near the elbow, never the hands or fingers.
Diabetic blood sugar tests are often taken from the fingertips, but there is a tendency for many new test devices to get away from this and use the arm because the fingertips are more pain sensitive than the arms.
I cannot think of any reason a blood test would have to be taken only from a single finger.
What are the major functions fo plasma proteins in the blood?
There are numerous kinds of proteins in the blood, thus proteins have many important functions. The major ones are:
- molecule transportation (Ex.: Lipoproteins make it possible for cholesterol to move freely in the aqueous environment of the organism);
- immunity;
- coagulation of blood (clots are made thanks to a reaction chain occurring between many kinds of proteins, the ''coagulation factors'');
- the maintain of oncotic pressure in blood vessels(oncotic pressure is a part of the osmotic pressure between the plasmatic and the lympatic environments).
Other functions exist, though.
Plasma proteins perform various functions. Plasma contains hundreds of proteins each having their specific function. A major protein is Albumin, which is responsible for transport of fatty acids, lipids, drugs etc in the body, it also maintains the osmotic balance with body. Albumin is followed by Immunoglobulins, which are responsible for the immune response. Fibrinogen is responsible for the blood clotting at the time of injury. There is a long list of proteins and an even longer list of their functions.
Is having small spots of brown blood menstruation?
Brown just means it is old blood, rather than fresh. A spotty, brown discharge during your period is a sign of an irregular period, and isn't necessarily abnormal. Many women experience it at least once in their lives, or even on a recurring basis. You can talk to your doc if you think there might be something wrong, or if you have abnormal pain.
How early can you have an HCG blood test done?
For best results:
* Take the test in the morning, if possible, because your hCG (pregnancy hormone) levels are at it's highest * Don't drink a bunch of fluids before taking the test because it will dilute your urine and can affect the results * Take the test no more than 1-2 days before expected period. Although some test say that you can see results up to 5 days before your missed period the percentage of accuracy is very low. * urinate for as long as possible on the foam like strip * wait for the results

No. For a child to have AB, one parent must have either A or AB and the other must have B or AB. O is a recessive type to both, so neither parent has any of those bloodtypes; their child will be O.
Why is there bleeding after urinating?
You could have a kidney or bladder infection. The only way to get rid of it is to see a doctor. Another possibility is a kidney or bladder stone. The stone forms in the kidney and causes bleeding as it travels down the ureter to the bladder. Once the stone is in the bladder it may not cause bleeding again until it begins to travel down the urethra when one urinates. Both infections and stones can be painful. Infections can be very dangerous if the kidney becomes involved. Similarly a stone trapped in the kidney could disastrously affect the production of urine. Medical attention is important if there is blood in the urine.

What are the causes of a high neutrophil count in cats?
Inflammation and infection are the causes of high neutrophils (white blood cells) in cats. The neutrophils eat 'enemy' cells like a little Pac-man, and die off after a day.
Tooth and kidney infections or cancers are common causes of high counts in older cats. Your veterinarian's review of the other items in the blood and urine tests can help determine which antibiotic or course of treatment will work best. Often it is as simple as a week-long course of Amoxicillan twice a day (the same bubble-gum pink stuff you got yourself as a kid).
A low neutrophil count is often a sign of leukemia, since the cat's body is not replenishing its daily supply of neutrophils. The cat will be more susceptible to infections of all types and will not be able to fight it off like normal.
