A pregnancy test can be performed early in pregnancy to predict conception or gestational age. Urine-based pregnancy tests detect pregnancy hormones in urine for a positive or negative result. Blood tests measure how much of a pregnancy hormone is present.
Qualitative Pregnancy Test – Urine
Home pregnancy test kits and urine pregnancy tests given by a physician are qualitative. Qualitative refers to the method of diagnosing pregnancy. Urine tests measure the presence of human chorionic gonadotropin (hCG) in urine. If hCG is present, the test results are positive. If no hCG is found in urine, the test will be negative.
False negatives are more common with a urine pregnancy test than false positives. False negatives can be caused by frequent urination due to high fluid intake and miscalculated start day of current menstrual cycle. False positives are typically linked to fertility treatments and prescription medications that include hCG as a means of increasing chance of conception.
Quantitative Pregnancy Test – Blood
A blood pregnancy test can be ordered as early as five to 10 days after unprotected intercourse. Blood pregnancy tests measure hCG levels in quantity rather than just a true or false result. Quantities can then be compared to normal levels as a means of gestational age prediction. In some cases, quantitative pregnant test results are higher than normal. Normal hCG levels at five weeks gestation fall between 18 and 7,340 mlU / ml. Measurements at the higher end of the range could mean medical issues with the pregnancy or multiple fetuses. Blood hCG levels will continue to rise until peaking between nine and 12 weeks gestation. After the 12th week, levels gradually fall until birth.
Medical Treatment and Pregnancy Test
Due to the possibility of false negative pregnancy test results, women who believe they may be pregnant should exercise caution when taking prescription and over the counter medications deemed unsafe during pregnancy. Diagnostic testing, such as X-rays and radiation-based testing should only be performed when medically necessary. Precautions include lead aprons placed over the abdominal area during X-rays. Prescription medications fall into pregnancy categories based on clinical testing and results. Categories include A, B, C, D and X.
Category A drugs have been thoroughly tested for use during pregnancy and deemed safe. Category B is designated after animal testing revealed no signs of fetal harm. Category C may be linked to fetal damage in animal testing. Category D includes drugs proven to cause harm to a human fetus, but benefits from medications in this category could outweigh risks. Category X is reserved for medications that should never be used during pregnancy.
distinguish between qualitative and quantitative model
Quantitative means it can be measured. Qualitative is something that is subjective meaning there is no way to really measure it. Example: Quantitative: 2=2=4 This is always true. Qualitative: Puppies are cute. (this is only an opinion. No facts)
Quantitative is based on measurements and numbers :)
Qualitative predictions are predictions based on quality. How effective is the product, or program expected to be? Quantitative predictions are based on quantities, in other words, numbers. How many people, products or units are expected.
Qualitative observation is subjective. Quantitative observation is the result of controlled testing procedures with prescribed procedures in place. Quantitative testing is sometimes called empirical testing.
what is the difference between qualitative and quantitative
Quantitative is like how many of the object there are, and qualitative is its color or texture (physical stuff).
Qualitative refers to what a sample is, while quantitative refers to how much of that materal is present.
The difference is that qualitative is wade with 1 of your 5 senses and the other one which is quantitative is an observation involving numbers.
yeah like
quantitive means amount, qualitative means quality or the integrity
A qualitative observation has to do with things you can't count, "The fish has black scales" is a qualitative observation. A quantitative observation has to do with things you can count, "The fish has 125 scales" is a quantitative observation. You can combine these two, an example would be "The fish has 125 black scales."
distinguish between qualitative and quantitative model
Qualitative usually refers to the quality of the work, how good, or bad, the work is. Quantitative refers to the amount, or quantity, of the work.
Qualitative test represents the substance and a quantitative test shows the amount.First Deals with descriptions, second one with numbers
Qualitative properties describes the physical aspects of an object such as the colour. Quantitative properties describe the numerical aspects of an object. Quantitative descriptions will always have a number in in it.
Quantitative means it can be measured. Qualitative is something that is subjective meaning there is no way to really measure it. Example: Quantitative: 2=2=4 This is always true. Qualitative: Puppies are cute. (this is only an opinion. No facts)
