diagnostic exams

Transvaginal ultrasound, also known as transvaginal or transvaginal ultrasound, is a diagnostic test that uses a small device that is inserted into the vagina and produces sound waves that are then transformed by the computer into images of the internal organs, such as the uterus, fallopian tubes, ovaries, cervix, and vagina

The hematocrit or Ht is a laboratory parameter that indicates the percentage of red cells, also known as red blood cells, red blood cells, and red blood cells, in the total blood volume, being important to identify and diagnose some situations, such as anemia. The hematocrit value may also reflect the amount of hemoglobin present in the red blood cells: when the hematocrit is low, it is usually indicative of some situation in which there is a decrease in the amount of red blood cells or hemoglobin, such as anemia, for example

Cardiac catheterization is a procedure that can be used to diagnose or treat heart disease. It consists of the introduction of a catheter, which is an extremely thin flexible tube, into the artery of the individual's arm or leg, which will be carried to the heart. Cardiac catheterization is also known as coronary angiography

C-reactive protein, also known as PCR, is a protein present in the blood that has its high concentrations mainly in inflammatory or infectious processes, and is usually one of the first indicators to be raised in a blood test. This protein is produced by the liver and can be used to assess the possibility of some infection, inflammatory processes and indicate a person's risk of developing cardiovascular disease

Bacterioscopy is a diagnostic technique that allows to identify quickly and in a simple way the occurrence of infections, because by means of specific staining techniques, it is possible to visualize the bacterial structures in the microscope. This test can be done with any biological material, and the doctor must indicate the material to be collected and analyzed, and the result indicates whether the presence or absence of bacteria, as well as their quantity and characteristics have been verified

The complete blood count is the blood test that evaluates the cells that make up the blood, such as leukocytes, known as white blood cells, red blood cells, also called red blood cells or erythrocytes, and platelets. The part of the hemogram that corresponds to the red cells is called an erythrogram, which, in addition to indicating the number of blood cells, tells about the quality of red blood cells, indicating if they are of the appropriate size or with recommended amounts of hemoglobin inside them

To do the breast self-examination is necessary to follow three main steps that include doing observation in front of the mirror, palpating the breast of the foot and repeat the palpation lying down. Breast self-examination is not considered one of the preventive tests for cancer, but it can be done once a month, every month, between the 3rd and 5th day after menstruation, which is when the breasts are more flaccid and painless, or on a fixed date in women who no longer have menstruation

The genetic test for breast cancer has as its main objective to verify the risk of developing breast cancer, in addition to allowing the doctor to know the mutation associated with the cancerous change. This type of test is usually indicated for people who have close relatives who were diagnosed with breast cancer before age 50, ovarian cancer or male breast cancer

The best test to identify breast cancer in the initial phase is mammography, which consists of an X-ray that allows you to see if there are lesions in the breast before the woman even has any symptoms of cancer, such as breast pain or fluid release through the nipple. See the 12 signs that may indicate breast cancer

Arterial blood gases are a blood test normally performed in-patient in an Intensive Care Unit that aims to verify that gas exchanges are occurring in the correct way and thus assess the need for extra oxygen. In addition, it is an examination that can be requested during hospitalization to assist in the diagnosis of respiratory, renal or serious infections, as well as to verify if the treatment is being effective and, therefore, can be used as one of the criteria that can influence the discharge of the patient

The diagnosis of meningitis is made through the clinical observation of the symptoms of the disease and confirmed by an examination called lumbar puncture, which consists of the removal of a small amount of cerebrospinal fluid from the vertebral canal. This test can show if there is inflammation in the meninges and what the causative agent is essential for the diagnosis and to direct the treatment of the disease

The cholinesterase test is a laboratory test mainly requested to check for poisoning or the person's degree of exposure to toxic products, such as pesticides, herbicides or fertilizers, for example. This test is more suitable for farmers, since they are in constant contact with agricultural products

The glucose test, also known as glucose test, is done with the purpose of checking the amount of blood sugar, being the main test performed to diagnose diabetes. See what are the symptoms of diabetes. To perform the test it is necessary that the person is fasting, so that the result is not influenced and the result can be a false positive for diabetes, for example

The best way to know if a person has HPV is through diagnostic tests that include observation of warts, pap smears, peniscopia, hybrid capture, colposcopy or blood test, which can be requested by the gynecologist in the case of the woman, or a urologist, in the case of man. When the HPV test result is positive, it means that the person has the virus but does not necessarily have cancer or symptoms and may not need to be treated

Platelets are small cell fragments derived from a cell produced by the bone marrow, the megakaryocyte. The process of producing megakaryocyte by bone marrow and platelet fragmentation lasts for about 10 days and is regulated by the hormone thrombopoietin, which is produced by the liver and kidneys. Platelets play an essential role in the process of platelet buffer formation, which is essential to avoid large bleeding, so it is important that the amount of circulating platelets in the body is within normal reference values

Taking the 6-minute walk test is a good way to discover the respiratory, heart, and metabolic capacity of a person who has a change in heart failure, chronic obstructive pulmonary disease, or who has had heart or lung surgery, for example. The main objective of the test is to check the distance that the person can walk for 6 minutes in a row, and to evaluate the cardiac and respiratory function, the person's heart rate and pressure must be measured before and after the test is performed

Digital mammography, also known as high resolution mammography, is done in the same way as conventional mammography, however, it is a more reliable method that saves images to the computer, there being less risk of image damage and need to repeat the examination. Thus, to make the digital mammography the woman should place the breast in the device that will make a slight pressure, which may cause some discomfort or pain

CA 27.29 is a protein that has increased its concentration in some situations, mainly in the recurrence of breast cancer, and is therefore considered a tumor marker. This marker has practically the same characteristics as the CA 15.3 marker, however it is more advantageous with respect to the early diagnosis of recurrence and non-response to treatment against breast cancer

The reference values ​​of the complete blood count generally vary according to the sex and age of the patient, however, it is also possible to observe differences in values ​​depending on the laboratory where the collection was made. The blood count is used to evaluate certain blood aspects such as red blood cells, leukocytes and platelets, and is a good way to identify the presence of infections, excess iron or anemia, for example. There

Platelets, also known as thrombocytes, are blood cells produced by the bone marrow and are responsible for the blood coagulation process, with increased platelet production when bleeding, for example, prevents excessive blood loss. The platelet reference value is between 150, 000 and 450, 000 platelets / μL of blood, however some conditions may interfere with the platelet production process, with increasing or decreasing blood concentrations, which is called thrombocytopenia.
