The **Array Chrome test** (Chromosomal Microarray Analysis / Array CGH) is an advanced genetic diagnostic test used primarily to evaluate pediatric health and developmental conditions. By scanning an individual's entire genome sequence at high resolution, it identifies tiny, sub-microscopic chromosomal abnormalities—specifically copy number variations (CNVs) like microdeletions or microduplications of DNA—that traditional karyotyping misses.
Healthcare providers commonly order this blood test for children displaying developmental delays, intellectual disabilities, autism spectrum disorders, unexplained seizures, or congenital malformations. Identifying these subtle genetic changes helps clinicians pinpoint underlying medical causes, tailor personalized treatment plans, and provide informed genetic counseling to families.

An **arsenic test** is a diagnostic laboratory procedure used to measure the concentration of toxic arsenic levels in the body. Healthcare providers typically order a 24-hour or spot **urine test** as the most reliable indicator of recent exposure, as inorganic arsenic clears rapidly from the bloodstream. **Blood tests** detect acute, immediate toxicity, while **hair and nail samples** reveal chronic exposure over preceding months.
Clinicians utilize these tests for individuals experiencing unexplained symptoms like abdominal pain, neuropathy, or skin changes, as well as those exposed to contaminated well water or industrial hazards.

An **Arthritis Basic Screening Test** is a panel of routine blood tests designed to detect inflammation, evaluate joint health, and identify underlying causes of joint pain and stiffness. The panel typically measures key inflammatory markers, such as **C-Reactive Protein (CRP)** and **Erythrocyte Sedimentation Rate (ESR)**, along with a **Rheumatoid Factor (RF)** test to help differentiate rheumatoid arthritis from other joint disorders. It often includes a **Uric Acid test** to evaluate for gout.
Clinicians use this basic profile as an initial diagnostic step to guide appropriate treatment, monitor disease progression, and refer patients to a rheumatologist.
