What does it mean to have a positive test result

A positive physical examination is generally an abnormal condition. According to the regulations of the medical routine, a negative is healthy, and a positive indicates that there is a problem with this physical examination indicator. Therefore, if the physical examination is positive, it is necessary to consider that you may be infected with some kind of disease, or that some result is abnormal.

For example, if you are positive for HIV antibodies, consider that you may have this HIV infection, and if it is negative, you may say that you do not have AIDS infection. In addition, if it is positive, it is recommended to seek further medical attention from a doctor in time to determine whether there is a problem. A positive result is usually problematic and requires further rediagnosis.

Be specific. What kind of checks?

Negative and positive controls are spoken for the "expected result". The group that was sure to produce the expected results was a positive control group. The group that certainly did not produce the expected results was a negative control group.

For example, to study the hypoglycemic effect of a certain drug A: the experimental subjects are diabetic mice, the method of administration is gavage, and the expected result is a decrease in blood glucose. If only the mice were given normal saline, it was a blank control group; If the mice were given drug A, it was a positive control group, and drug A lowered blood sugar; If the mice were only given glucose water, it was a negative control group, and the blood sugar would not only not drop, but would rise.

In the physical examination, the negative is generally Du represents normal, and the positive represents Zhi

The table is sick or has a virus.

Negative and positive. Obligate is used more in medicine and has become a term that refers to the presence or absence of a certain examination, or is used to indicate the results of a certain examination, and is commonly used in the following ways:

1. Indicate the results of the physical examination: If someone suffers from coronary heart disease or tuberculosis of a small range, the doctor may not be able to find the problem during auscultation, so he will say that there are no positive signs of heart and lungs, or say that the heart and lungs are negative, or write it as heart and lung (-).

2. Indicate the results of the test: do the tuberculin test, if there is no local redness and swelling, it is called ot (-) indicating that there is no immunity to tuberculosis bacteria, and BCG should be vaccinated.

3. Indicate the results of the laboratory test: hepatitis B "two and a half" test. If the E antigen is positive (+), it is highly infectious, and if it is only positive for surface antibodies (+), it is immune to the hepatitis B virus, and it is generally not infectious.

In various medical tests, a positive result generally indicates that the target has been found, the expected result has been obtained, etc. For example, during urinalysis, protein (+) indicates that protein was found in the urine; Another example is to check the neuropathic reflexes:

The Babinski reflex (+) indicates that this pathological sign is eliminated. Negative indicates that it has not been detected, or that it has not been elicited. However, a positive negative does not indicate whether it is normal or not.

Both of these cases are indicated. However, some positive tests indicate normal, such as the Rinne test in the hearing test, which is positive. Test results are generally divided into two categories: qualitative results and quantitative results.

The so-called qualitative, that is, the test result is an indication of the presence or absence of the substance being tested, and the result is reported in the form of "negative" and "positive". The results of the two halves of the liver are reported in a qualitative manner. Sometimes "negative" and "positive" are also denoted by "and" ".

It is important to note that the " " here does not represent the strength of the positive result, but is only a qualitative concept. Sometimes, the "number of "also reflects a semi-quantitative result." For example, on a routine stool test form, there are sometimes results such as "white blood cells", in which case the number of white blood cells is proportional to the number of white blood cells observed by microscopic magnification.

The other type of test sheet is to report the results in a quantitative way, which is presented as a specific value with an arrow after the specific value. " indicates that it is higher than the upper limit of the reference range, " means that it is lower than the lower limit of the reference range, and it is often followed by a reference range, which can be used to determine whether the test result is normal or not when reading.

--- test to report on the report, the negative result is from.

Indicates that no BAI has been detected (or very little has been detected) of a specific DU substance or ZHI is a microorganism, a positive indicates that a DAO has been detected, and a strong positive indicates that a large amount has been detected. For example, a two-and-a-half test for hepatitis B includes five indicators, each representing a substance (antigen is a protein of the virus, an antibody is a protein produced by you in response to an antigen), and a positive one means that it has been detected. The pregnancy test you are talking about is the detection of chorionic gonadotropin (HCG), which can be detected in the urine on the seventh day of a woman's pregnancy, which causes the placenta to be produced.

If this test is positive, it means that HCG has been detected, and it is likely that she is pregnant, but it is also possible that she has other diseases. If it is negative, it means that it has not been detected, but it does not mean that you are not pregnant!

- A negative on the medical examination form means that no abnormal symptoms were detected, and a positive one means that there are abnormal symptoms (which is the case in most cases).

When in doubt, consult a medical professional!

The items that come from the physical examination are positive, indicating that the body exists since.

disease, which requires further investigation.

If it is negative, it means that there is no problem and the test result is normal. However, the test for hepatitis B is the opposite, if it is positive, it means that there are antibodies in the body, and there is also a urine routine test, and if the test result is negative, it means that it is normal, if it is positive, it may be a kidney infection, but in most cases, a negative result is a normal result.

A negative physical examination indicates that there is no related disease, which indicates that there is no problem, a positive one indicates that there is a disease, and a positive one indicates that there is a problem, and only a positive case is good, such as a positive hepatitis B surface antibody, indicating resistance to hepatitis B.

Hello, masculine table bai

There are many kinds, and you should be clear about what the positive indicators are.

Suggestions: Generally speaking, the positive characteristics obtained by checking the blood DAO have hepatitis B surface antigen, which is also the most commonly checked item during the physical examination, and this positive may indicate that you have hepatitis B, so there are restrictions on applying for some colleges.

Life care: It is recommended that you check the checklist to see what the items are, and if it is above, you can go to a large hospital for a review.

Reacting with the test sample is positive, indicating abnormality.

Negative means that it does not react with the test sample, which is a normal situation.

Positivity generally refers to the detection of positive new coronavirus virus infection by nuclear acid, and the person who is positive can generally be comforted by paying attention to a reasonable diet, regulating his psychological emotions reasonably, and doing a good job of preventive work.

1. Reasonable diet: During the period of illness, patients infected with the new crown need to pay attention to ensure the nutritional balance of their daily diet, and ensure that they can fully consume the energy, egg white matter, vitamins and trace elements required by the body.

2. Rational regulation of psychological and emotional conditions: It is also possible to do a good job in the psychological care of the new crown infection, which is also a particularly important thing for the new crown infection. The patients themselves should first of all have a correct understanding of the disease and face the disease with a positive and optimistic attitude.

3. Do a good job of prevention: Because the new coronavirus infection is contagious, the new crown infected person must pay attention to self-protection and isolation work after suffering from the disease, and need to wear a mask 24 hours a day. Family visits and escorts are strictly prohibited during hospitalization.

It is necessary to maintain good personal and environmental hygiene, balanced nutrition, moderate exercise, adequate rest, and avoid excessive fatigue.

1. Male friends:

1. Isolation alone: Positive patients can be isolated at home, but they should not go out and refuse all visits. At the same time, they should live alone in a well-ventilated room, and separate clothing, tableware and other items from the same person;

2. Physical observation: During the isolation period, the patient should pay attention to the changes in personal physical symptoms, such as whether the body temperature rises, whether the throat is painful, etc.;

3. Pharmacological treatment: If there is no obvious discomfort in the body, pay attention to rest. However, if there is obvious discomfort, you can follow the doctor's instructions for medical treatment, such as fever, headache, sore throat and obviously affect rest and sleep, you can use antipyretic and analgesic drugs, and if you have cough symptoms, you can use compound fresh bamboo drainage, etc.;

4. Life conditioning: patients need to drink more warm water and fully supplement sleep, and it is recommended to choose foods that are easy to digest and rich in nutrients, such as chicken custard, shrimp porridge, etc.;

5. Medical treatment: If the patient has obvious abnormalities, such as high fever that lasts for more than 2 days after taking antipyretics, body temperature of 35 or below, convulsions, difficulty breathing or shortness of breath, aphasia or inability to move, etc., if the patient needs to seek medical treatment in time, he can directly call the emergency phone or choose the appropriate way to go to the medical institution for treatment.

2. For me:

1. The test result is negative: if the test result is negative, there is generally no need for special treatment, do a good job of daily protection, and live normally, work, and study without being too anxious;

2. The test result is positive: If the test result is positive, it means that the new coronavirus has been infected, and the same measures as the positive friends mentioned above need to be taken.

What does positivity mean

Negative and positive are often used in medicine, and are commonly used terms to refer to the presence or absence of Liang Yu, or to indicate the results of a certain examination of the rubber nucleus segment. In medical terms, a positive one generally means that one is sick or has a virus, and one negative one is normal. If someone has coronary heart disease or tuberculosis of a small range, the doctor may not be able to detect the problem on auscultation, so he or she will say that there are no positive signs of the heart or lungs, or that the heart and lungs are negative.

In addition, if the composition of kidney stones is calcium oxalate, the shadow is very deep when the film is taken, which is called a positive stone, and the component of kidney stones is uric acid, and the shadow is very light, which is called a negative stone.

What does it mean to be positive: sick or have a virus.

Explanation: Generally speaking, positive means sick or virus, and negative means normal. Negative and positive are used a lot in medicine and have become a term that refers to the presence or absence or to indicate the results of a certain examination.

In addition, there are quite complex situations such as false negatives and false positives, which should be judged separately according to the specific circumstances of each person. And quite a few people always think that being negative is better than being positive, which is a misconception.

Indicates the results of the physical examination: If someone has coronary heart disease or tuberculosis of a small range, the doctor may not be able to detect the problem on auscultation, so he or she will say that there are no positive signs of the heart or lungs, or that the heart and lungs are negative, or that it is written as heart and lung (-).

Indicates the disadvantages of the test: do the tuberculin test, if there is no local redness and swelling, it is called ot (-) indicating that there is no immunity to tuberculosis bacteria, and BCG should be vaccinated.

Indicates the results of the test: Hepatitis B virus is tested in two and a half tests, such as E antigen positive (+) indicates that it is highly infectious, and if only surface antibody positive (+) indicates immunity to hepatitis B virus, it is generally not infectious.

Indicates the results of filming: if the component of kidney stones is calcium oxalate, the shadow is very deep when the film is taken, which is called a positive stone, and the gout patient is called a negative stone because the component of the branch-based kidney stone is uric acid, and the shadow is very light.
