ZFirst Folic Acid (FA) Assay Kit: Quantum Dot Technology, Precisely Targeting the Foundation of Health in the Early Stages of Life
Folic Acid (Folic Acid) is a key coenzyme for DNA synthesis and cell division, and is crucial for red blood cell development and the construction of the fetal nervous system. ZFirst employs the innovative Quantum Dot Immuno-Fluorescence Method (QD-FIA) to achieve the capture and precise quantification of serum folic acid at extremely low concentrations. It is an essential tool for perinatal nutritional assessment, diagnosis of megaloblastic anemia, and management of H-type hypertension. 

Core Advantages (Why Choose ZFirst FA)
Outstanding Sensitivity Driven by Quantum Dots: Utilizing the extremely high brightness and stability of quantum dot (Quantum Dot) nanomaterials, the detection limit of these quantum dots is far superior to that of ordinary fluorescent reagents. Even at extremely low concentrations, they can output stable and precise quantitative values, effectively avoiding missed diagnoses.
Core Indicators for Optimal Fertility and Pregnancy: Folate levels are a key reference for preventing neural tube defects (NTD) in fetuses. The ZFirst kit provides an immediate and reliable screening method for gynecology and obstetrics, facilitating precise nutritional intervention during preconception and pregnancy.
POCT Instant Results: Compatible with the ZFirst fluorescence analyzer, from sample addition to the production of full quantitative results, it only takes 15 - 20 minutes. The operation is extremely simple and is highly suitable for small and medium-sized laboratories, maternity and health care hospitals, and clinics.
Extremely Strong Anti-interference Ability: Quantum dot technology can effectively shield the interference of sample background fluorescence, demonstrating excellent consistency and repeatability (CV < 10%) in both serum and plasma samples.
Integrated Packaging Design: Each box contains 25 independent test cards for individual use, along with an ID chip that automatically records batch information. The wide temperature storage range of 2℃ - 30℃ reduces the cost of cold chain logistics and ensures global export quality.

Product Overview (Summary)

The ZFirst Folic Acid Test Kit uses advanced Quantum Dot Fluorescence Immunoassay (QD-FIA) technology to provide rapid, fully quantitative measurements of serum and plasma folate levels. Engineered for high-precision diagnostic routines, the ZFirst Folic Acid Test Kit helps healthcare providers monitor perinatal maternal nutrition, diagnose megaloblastic anemia, and manage hyperhomocysteinemia in H-type hypertension. Delivering results within 15 to 20 minutes, this kit combines point-of-care convenience with central-laboratory accuracy. Beijing Jiachuang Jiuhe Global Trade Co., Ltd offers the ZFirst Folic Acid Test Kit to global distributors and laboratories seeking cost-effective, high-sensitivity diagnostic reagents to enhance clinical decision-making.

Comprehensive Product Description

The ZFirst Folic Acid Test Kit is a professional quantitative diagnostic reagent designed to meet the growing demand for accurate prenatal nutrition monitoring and cardiovascular disease management. Folic acid, or Vitamin B9, is essential for one-carbon metabolism, DNA synthesis, and cellular replication. Adequate folic acid intake during preconception and early pregnancy prevents neural tube defects in developing fetuses. Furthermore, low folic acid levels contribute to elevated plasma homocysteine, increasing the risk of H-type hypertension and megaloblastic anemia.

Traditional folic acid diagnostic methods, such as microbiological assays or conventional ELISA, often require labor-intensive processing, long incubation times, and sensitive cold-chain storage. The ZFirst Folic Acid Test Kit solves these operational challenges by incorporating semiconductor quantum dot nanomaterials into an immunofluorometric test platform.

Designed for point-of-care testing and routine laboratory use, each ZFirst Folic Acid Test Kit is supplied in a single-person cassette format (25 tests/box) with a dedicated lot ID chip. When paired with the ZFirst series fluorescence immunoassay analyzer, the ZFirst Folic Acid Test Kit eliminates manual measurement steps, reduces human error, and speeds up diagnostic workflows in obstetrics, cardiology, and general medicine.

Key Product Features

• High Sensitivity Quantum Dot Technology: Utilizes quantum dot nanomaterials with high luminescence intensity to ensure accurate measurement of low serum folic acid concentrations.

• Rapid POCT Turnaround: Produces fully quantitative folic acid results in 15 to 20 minutes, allowing real-time clinical decisions during outpatient visits.

• Strong Anti-Interference Performance: Minimizes background autofluorescence from serum and plasma, delivering a coefficient of variation (CV) under 10%.

• Flexible Ambient Storage: Stable at storage temperatures between 2°C and 30°C, lowering global shipping costs and reducing cold-chain storage needs.

• Single-Use Cassette Packaging: Packaged in 25-test boxes with individual test cassettes and automatic calibration ID chips to avoid reagent waste.

Because folic acid is a low-molecular-weight hapten present at nanomolar concentrations in human blood, precise binding detection requires a high signal-to-noise ratio. Quantum dots possess broad excitation profiles and narrow emission peaks, allowing excitation by light sources without spectral overlap into the detection channel.

The ZFirst Folic Acid Test Kit uses these stable fluorophores to capture low analyte concentrations while resisting photobleaching. By eliminating matrix interference common in hemolyzed or lipemic blood samples, the ZFirst Folic Acid Test Kit maintains consistent accuracy across varied clinical specimen types.
