What is a progesterone test? Progesterone is a hormone that's made mainly by the ovaries, which are two glands in the female reproductive system that contain eggs. Progesterone plays an essential role in the female reproductive system. It regulates the menstrual cycle, prepares the uterus for pregnancy, and helps maintain a healthy pregnancy. However, an imbalance in progesterone levels can l...
What is this test? E2 plays a key role in the development of the female reproduction system, including the uterus, fallopian tubes, vagina, and breasts. Women have higher amounts of E2 during their reproductive years and almost none after menopause. Other estrogens include estrone and estriol. Estrone is the main estrogen made during menopause. In men, E2 is secreted in moderate amounts by the tes...
Detection principle: ELISA: Use enzyme-labeled antibodies or antigens to produce chromogenic products through enzyme catalysis, and then quantitatively analyze target molecules by measuring the optical density of the chromogenic products. CLIA: Directly detects the light produced by a chemiluminescent reaction, without the need for enzyme catalysis, and uses a chemiluminescent substr...
Procalcitonin (procalcitonin) is a glycoprotein composed of 116 amino acids with a molecular weight of about 12.7kD. It is a propeptide of calcitonin with no hormone activity. PCT is expressed by neuroendocrine cells (including C cells of thyroid, lung and pancreas tissues) and decomposed into (immature) calcitonin, carboxyl-terminal peptide and amino-terminal peptide. 1. Biological characteristic...
WHAT is Folic Acid (Folate)? If you are pregnant, your doctor has likely suggested that you take Folic Acid pills. But do you know why? Folic Acid is a type of vitamin, also known as vitamin B9. Folic Acid is used to: · Make and repair DNA · Prevent birth defects of the spinal cord and brain (neural tube defects) · Produce red blood cells (Referen...
Poclight: Glycated Hemoglobin Detection Solution 1. What is Glycated Hemoglobin? Recent data shows that there are currently about 114 million diabetes patients and 500 million people in prediabetes in China. According to the Chinese Type 2 Diabetes Prevention and Treatment Guidelines (2020 edition), in type 2 diabetes, diagnosis also requires testing of patients' random blood glucose (RP...
Pre-eclampsia What is Pre-eclampsia? Preeclampsia is a pregnancy-related condition characterized by extensive endothelial dysfunction and vasospasm, typically manifesting after 20 weeks of gestation and occasionally extending up to 4-6 weeks after childbirth. Clinically, it is identified by the onset of hypertension and proteinuria, with or without severe complications (Medscape, 2022). Early sign...
Homogeneous chemiluminescence is an important milestone in chemiluminescent immunoassay, enabling direct chemiluminescent detection without the need for separation and washing steps. It has garnered significant attention and wide application in various fields such as basic medical research, serum biomarker detection, and drug screening. In order to improve the coverage and quality of medica...
