count

 [kownt]
a numerical computation or indication.
Addis count the determination of the number of erythrocytes, leukocytes, epithelial cells, and casts, and the protein content in an aliquot of a 12-hour urine specimen; used in the diagnosis and management of kidney disease.
blood count (blood cell count) see blood count.
blood count, complete a series of tests of the peripheral blood, including the erythrocyte count, erythrocyte indices, leukocyte counts, and sometimes platelet count.
blood count, differential differential leukocyte count.
erythrocyte count determination of the number of erythrocytes in a unit volume of blood that has been diluted in an isotonic solution, done with an automatic counter such as a flow cytometer. Called also red blood cell or red cell count.
leukocyte count determination of the number of leukocytes in a unit volume of blood, usually after the erythrocytes have been lysed and the blood has been diluted; it may be done either manually with a hemacytometer or electronically. See total leukocyte c. and differential leukocyte c. Called also white blood cell or white cell count.
leukocyte count, differential a leukocyte count that calculates the percentages of different types. See also total leukocyte count.
leukocyte count, total a leukocyte count measuring the total number of all the types in a given volume of blood. See also differential leukocyte count.
platelet count determination of the total number of platelets per cubic millimeter of blood; the direct platelet count simply counts the cells using a microscope, and the indirect platelet count determines the ratio of platelets to erythrocytes on a peripheral blood smear and computes the number of platelets from the erythrocyte count.
red blood cell count (red cell count) erythrocyte count.
reticulocyte count a calculation of the number of reticulocytes in 1 cu mm of peripheral blood, recorded either as an absolute number or as the percentage of the erythrocyte count. It provides a means of assessing the erythropoietic activity of the bone marrow.
white blood cell count (white cell count) leukocyte count.

1. A reckoning, enumeration, or accounting.
2. To enumerate or score.

count

(kount) a numerical computation or indication.
Addis count  determining the number of erythrocytes, leukocytes, epithelial cells, casts, and protein content in an aliquot of a 12-hour urine specimen.
blood count , blood cell count determining the number of formed elements in a cubic millimeter of blood; it may be a complete blood count or it may measure just one of the formed elements.
complete blood count  a series of tests of the peripheral blood, including the hematocrit, the amount of hemoglobin, and counts of each type of formed element.
differential leukocyte count  a count on a stained blood smear of the proportion of different types of leukocytes (or other cells), expressed in percentages.
platelet count  determination of the total number of platelets per cubic millimeter of blood; the direct platelet c. simply counts the cells using a microscope, and the indirect platelet c. determines the ratio of platelets to erythrocytes on a peripheral blood smear and computes the number of platelets from the erythrocyte count.

count

Etymology: L, computere, to calculate
a computation of the number of objects or elements present per unit of measurement. Kinds of counts include Addis count, bacterial count, complete blood count, and platelet count.

count

Lab medicine The enumeration of a thing. See Absolute eosinophil count, Bacterial count, CD4 count, Colony count, Collateral frame count, Differential count, Platelet count, Pollen count, Red cell count, Reticulocyte count, Sperm count, White cell count Surgery A needle and instrument count. See Sponge count.

count

(kownt)
1. A reckoning, enumeration, or accounting.
2. To enumerate or score.
3. A tally of instruments and materials performed at the beginning of a surgical operation and again before the incision is closed, to ensure that no foreign object remains in the patient.

count

a numerical computation or indication.

differential count
a count, on a stained blood smear, of the proportion of different types of leukocytes (or other cells), previously expressed in percentages but now usually reported in absolute numbers (109/l) for a better indication of abnormalities that may exist.
milk cell count
platelet count
the count of the total number of platelets per liter (109/l) of blood by counting the platelets in a counting chamber, a hematology analyzer, or by estimating the number on a stained blood smear.
sperm count
see semen concentration.
total bacterial count
determination of the total number of bacteria in the sample examined microscopically, then a calculation of the number per ml. These do not distinguish between viable and non-viable organisms. See also breed's direct smear method.
viable bacterial cell count
enumerating the number of viable bacteria present in a sample based on counting the number of colonies from a given dilution.
wool count
an arbitrary number given to wool to indicate its fiber diameter, e.g. 60's, based on an eyeball assessment of the number of hanks of yarn that could be spun from one pound of wool. Now superseded by measurement of the diameter, e.g. 20 microns.
worm count
a total worm count requires a freshly slaughtered cadaver, collection of intestinal or other fluid in an aliquot sample; in the case of lungs it is necessary to digest the tissue; counting actual worms and by multiplication measuring the total worm burden.

Patient discussion about count

Q. When do you start counting your pregnancy? I want to know if after your last period you start counting your months of pregnancy.

A. so many doctors are counting from your last menstrual day.
so if you had your last menstrual period on 30 october 2008, and today is 5 december 2008, and you check yourself is positively pregnant -- it means you are 5 weeks pregnant already.

Q. how do i teat my no sperm count? i do not have a live sperm,how can i treat and have live sperm count

A. The treatment is done only at specialist centers, and consists first of evaluation of the reason for this condition (called azoospermia). If an anatomical malformation is found, it may be corrected, as well as medical conditions, and in some cases, direct extraction of sperms from the testes (called MESA) enables in-vitro fertilization.

Q. what is the counting diet? when you count your calories of every meal during the day? why is it so papular?

A. because you get so frustrated of counting calories all the time that you rather skip meals :)
yes it's counting calories, and it's popular because at the end our body cannot defy the laws of thermodynamics- if you eat 4000 calories a day and use only 3000, the rest will transform into fat. and in this diet it doesn't matter what you eat as long as you don't go over the calorie level you decided. not always a healthy diet if done without someone supervising it.
