In study of 832 clients, TSH poorly correlated with hypothyroidism

study evaluated 6 tests for HGH deficiency diagnosis.  Ninety-five percent specificity found with ARG + l-DOPA and ARG alone.  However, the authors found a 95% specificity with IGF-1 < 77.  Although, IGF-1 is false negative in up to 65% of those with HGH deficiency.

good review of the physiology behind adolescent PCOS.  Though I hate this term because it treats PCOS as a diagnostic disease when it is simply a metabolically induced hormone balance.

CT Angiography or CTA stands for "Computed Tomography Angiography". It is a computed tomography technique which is mainly used to study the arteries and veins of the body. City x-ray and Scan Clinic (P) Ltd is one of the best diagnostic center in Delhi, which offers best CT Angiography facilities. You can book a test and get the reports online. Here you will have Somatom Definition AS 194 slice/sec most advanced Multi Slice Spiral CT Scanner from Siemens.

Not a research article, but nice graphic with accompanied review.

Nice article review.

Britain's biotech firm Avacta Group on Monday (January 10) announced halting sales of its Covid-19 rapid antigen lateral flow test AffiDX to replace antibodies in the device and increase its ability to diagnose the Omicron variant. The company stated that AffiDX is capable of detecting Omicron when the virus is present in high numbers in samples, but the sensitivity of the test reduces at lower viral loads. The performance of all rapid antigen tests came under scanner in wake of a large number of mutations in the Omicron variant. AffiDX contains both a proprietary Affimer reagent and a commercially available antibody. The Affimer reagent detects the Omicron variant with the same sensitivity as the Delta variant, and performance of the antibody is paired with the Affimer reagent in the test. This has been affected by the additional Omicron mutations, the firm said. Alastair Smith, chief executive of Avacta Group, said: "Our determination to only provide high quality, high performance diagnostic tests has led us to the correct decision to pause all marketing of the AffiDX® lateral flow antigen test. We have, of course, been unable to market the product in the UK since October 2021, as the product continues to await approval under the new CTDA regulatory process.

Hysteroscopy is a less-invasive diagnostic procedure in fertility treatments like in vitro fertilization (IVF). The process involves inserting a small, lighted telescope known as a hysteroscope through the vagina and cervix and into the uterus. Lets explore the role of hysteroscopy in IVF, benefits, Risks, procedure etc.

heat shock proteins (HSP) and cancer.  They can be useful as biomarkers for some specific cancers.  HSP are normally biologically active, but are increased in cancer.

salivary testosterone, as measured by LC-MS and ELISA, showed strong correlation with serum free "calculated" testosterone.

Good discuss of androgen deficiency in women.  Also, good discussion of SHBG.  

ER beta and prostate cancer.  More aggressive prostate cancer is found to be associated with lower ER beta expression in the prostate.  this makes sense, as other studies have shown that ER beta in the prostate can induce apoptosis (cell death), which is a powerful mechanism to regulate uncontrolled growth as found in cancer.

salivary testosterone found to correlate will with blood free testosterone in men.

hypothyroidism and hyponatraemia.  Interesting point that the patient was started on T4/T3 therapy.

Good review of lab perspective on EBV.

salivary cortisol found to be superior to total serum cortisol levels.

NIH supports saliva testing.

saliva testing is the new "gold standard" for hormone evaluation.  No testing method is perfect and thus there are guidelines for salivary collections.  However, saliva is equal too or superior to blood for hormone evaluation.

radiation from mammograms shown to increase cancer risk in those with BRCA mutations. IN this cohort, the risk was found in those under 30 years of age. In this study, they suggested MRI as a safer alternative. But, what about thermograms?
