Quantitative determination of amino acid profile in plasma/serum by LC-MS/MS technique
-
Test objective: To determine the concentration of amino acids in the test material. This allows for an assessment of the body's amino acid supply in order to develop a diet that ensures adequate levels of amino acid intake over time:
- elimination diet
- vegan or vegeterian diet
- sports training
- amino acid supplementation (BCAA, Beta-alanine, methionine, tyrosine)
- increased demand (pregnancy, growth period, cancer, convalescence)
- Method of testing: High-performance liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS)
- Analysed substances: Alanine (Ala), Arginine (Arg), Asparagine (Asn), Aspartic acid (Asp), Beta-alanine (bAla), Citrulline (Cit), Glutamic acid (Glu), Glutamine (Gln), Glycine (Gly), Histidine (His), Homoarginine (hArg), Isoleucine (Ile), Leucine (Leu), Lysine (Lys), Methionine (Met), Ornithine (Orn,) Phenylalanine (Phe), Proline (Pro), Sarcosine (Sar), Serine (Ser), Threonine (Thr), Tryptophan (Trp), Tyrosine (Tyr), Valine (Val), Taurine (Tau), Gamma-aminobutyric acid (GABA).
- Type of test material: Dried blood spot, serum, plasma
- Test category: DBS, Metabolomics
Amino acid profile testing from dried blood spot — patient-centric sampling
Masdiag Laboratory offers full amino acid profile (26 amino acids) analysis from dried blood spot (DBS) using validated LC-MS/MS methodology. DBS is a patient-centric sampling approach — the patient collects a few drops of capillary blood at home with a simple finger prick, dries the sample on filter paper, and ships it to our laboratory via standard post. No clinic visit. No cold chain. No venipuncture.
This approach is increasingly adopted by supplement companies, nutraceutical brands, health tech platforms and clinical research organisations as a scalable, convenient alternative to conventional blood testing.
Test material: Dried blood spot (DBS), serum, plasma | Method: LC-MS/MS | ISO 15189 compliant | Available for: individual patients · nutrition programmes · metabolic disorder clinics · international partners
