Vitamin D (VD) is well-known for its role in calcium and bone metabolism, being one of the essential micronutrients for maintaining human health. In recent years, substantial evidence has emerged indicating that VD, as a novel immunoregulatory hormone, not only influences bone and calcium metabolism but also partakes in metabolism and immune regulation through various atypical mechanisms such as antioxidative stress, cell proliferation, differentiation, and apoptosis. VD impacts nearly all body tissues and is closely related to endocrine, autoimmune, and other diseases, demonstrating its multifaceted non-skeletal functions. FiCA 25-OH-VD is a fluorescence immunoassay (FIA) for quantitative determination of 25-Hydroxyvitamin D (25-OH-VD) in human serum, plasma, and whole blood samples. It is mainly used clinically to assist in the diagnosis of vitamin D deficiency related diseases.

Hormones are substances that send chemical messages in the body and have a variety of effects on processes like physical development, reproduction, and mood. People of any sex have a wide range of hormones in their body. Hormone testing for women and people assigned female at birth often focuses on hormones that play a role in puberty, fertility, menopause, and health conditions more common in this population. Hormone tests for women can be used to confirm pregnancy, track menopause, detect hormonal imbalances, and understand the cause of reproductive health issues.

In WHO consolidated guidelines on tuberculosis 2021, Computer-aided detection (CAD) is being recommended for the first time as an alternative to human interpretation of digital chest X-ray (CXR) for TB screening and triage in individuals aged 15 years or older. CAD technology involves using computer algorithms to assist in the interpretation of medical imaging, such as chest X-rays, for TB detection. Evaluations indicates that CAD software programmes are accurate and their performance compares well with human interpretation of CXR for detection of TB disease. CAD systems can analyze large volumes of images rapidly, facilitating mass screening and timely diagnosis and intervention. Moreover, CAD technology can reduce reliance on highly trained medical personnel for interpretation, has the potential to standardize interpretation, reducing intra- and inter-reader variability.

What is an IGF-1 test?This test measures the amount of IGF-1 (insulin-like growth factor 1) in your blood. IGF-1 is a hormone that manages the effects of growth hormone (GH) in your body. Together, IGF-1 and GH promote normal growth of bones and tissues. GH levels in the blood fluctuate throughout the day depending on your diet and activity levels. But IGF-1 levels remain stable. So, an IGF-1 test is a useful way to find out if your body is making a normal amount of GH.

TORCH is an acronym for a group of four infectious diseases that may cause illness in pregnant women and may cause birth defects in their newborns depending on the stage of pregnancy when the mother is infected. The tests are a screen for the presence of any of the antibodies to these infections. Confirmation of an active infection may require more specific tests.
