The basic principle of semi-quantitative test paper and ordinary ovulation test paper is to capture a pulse (peak) of LH (luteinizing hormone) that must appear before ovulation. When this peak is reached, ovulation will occur within 24 hours. Being able to capture this (peak) more accurately can greatly improve the pregnancy rate.
When capturing this peak, the technology and parameters used by semi-quantitative test paper and ordinary ovulation test paper are very different:
1, using different technologies.
Colloidal gold technology is used for ordinary ovulation test paper, and monoclonal antibody is used for semi-quantitative test paper to measure ovulation. Semi-quantitative test paper adopts monoclonal antibody immunochromatography technology, and the peak LH level captured by semi-quantitative test paper is much more accurate than that captured by ordinary test paper, so the chances of pregnancy success are greater.
2.LH detection range and sensitivity are different.
The semi-quantitative use of monoclonal antibodies is more advanced and sensitive. The detection range of LH concentration by test paper is 0-65mIU/ml, with high sensitivity, which can not only find the ovulation period, but also accurately find the ovulation date.
The detection range of LH concentration by ordinary ovulation test paper is 0-25mIU/ml, and the sensitivity is relatively low. It can find the ovulation period, but it can't find the exact ovulation date.
3. The parameter values on the left are different.
The detection standard of common ovulation test paper is the LH level of European and American women, and the detection standard of semi-quantitative test paper should be the LH (luteinizing hormone) level of China women, which is more accurate and can help China women catch the correct LH (luteinizing hormone) pulse (peak)!
The semi-quantitative test paper varies from person to person, and can find the specific value of each person's own LH level. When ordinary ovulation test paper detects LH, it doesn't know its LH level, only the color of the test line. Semi-quantitative test paper overcomes this deficiency, and it can find specific values by using "color code".
4. Different interpretations of the results.
Semi-quantitative ovulation test paper can not only show that the strong yang has found the ovulation date, but also find out more women's health and ovulation problems. For example, for people with cycle disorder of more than 40 days, polycystic and elderly people, it is difficult to monitor ovulation date with ordinary test paper, while semi-quantitative test paper can.
The results of ordinary test paper are generally negative and positive. Negative means that only the control line has no detection line, indicating that there is no sign of ovulation or the ovulation peak has passed or the test paper is invalid. Positive is divided into strong yang and weak yang. When yang is strong, the two lines are the same color, indicating that ovulation will occur within 24-48 hours. When yang is weak, there are two bars, one deep and one shallow, indicating that ovulation has not yet arrived.
Second, how to choose ovulation test paper
1, marking package
(1) In order to ensure the quality, it is recommended to buy it in a regular pharmacy.
The state has clear regulations on the production, marketing and packaging of drugs. The drug packaging label of ovulation test paper should indicate the drug name, specification, storage, production date, production batch number, validity period, approval number, production enterprise and other necessary contents, including packaging quantity, transportation precautions or other signs.
(2) Drug instructions are the most detailed information of drugs.
It includes all kinds of information that patients want to know about this drug, such as its shape, performance, indications, usage, dosage, side effects, precautions and other related contents. Therefore, when purchasing drugs, you must read the instructions in detail. It is necessary to see clearly the ingredients and indications of the drug, as well as the trademark and production date. The most important thing is to determine whether there is an approval number on the package, which is the legal sign that the country approves the production of this drug.
(3) The appearance shall be smooth and complete, with uniform thickness, without spots, black spots, fragments, mold growth and peculiar smell.
Yellowing, with dark spots and spots, uneven surface, cracking, adhesion and peculiar smell, serious mottling, mildew, broken sugar coating, adhesion and so on. , and is suspected to be counterfeit and inferior drugs.
2, it is good to be suitable.
(1) Differentiate symptoms
Before buying ovulation test paper, you should first understand your physical condition and then judge your needs. If you can't tell the symptoms clearly, go to the hospital and buy under the guidance of a doctor.
(2) Buy in moderation
Before buying, it is best to consult a doctor or pharmacist about the use of ovulation test paper before deciding the purchase amount. Generally, different brands of ovulation test paper may have different regulations.
(3) Pay attention to price and practicality
Some people always think that high prices are good and buy blindly. Some people only pay attention to low prices, but not to product quality. These two kinds of purchases are one-sided, and we should also pay attention to the purchase of ovulation test paper, an important product.
It is best to remember the following three points:
At first glance:
When buying, mothers should carefully check whether the business unit has the relevant business license, and do not buy from individuals or units without business licenses.
Second inspection:
When buying, mothers should carefully check the relevant information of the products, such as the license number of the production enterprise printed on the packaging, the product registration certificate number, the product description and certificate of conformity of the products packaged with the products.
Three questions:
If the ovulation test paper is not clear, it is best to consult medical staff and buy it under the guidance of a doctor. When purchasing, you should carefully ask about the usage, precautions, contraindications and mechanism of action of the product to prevent misuse.
