 What is the meaning of Type 3A Kidney Disease? 

seems there might be a confusion in the terminology you provided. Kidney diseases are typically classified using different systems, such as the stages of chronic kidney disease (CKD) or specific diagnoses such as glomerulonephritis or polycystic kidney disease. 

The term "Type 3A kidney disease" doesn't correspond to a recognized classification in nephrology. However, if you're referring to Stage 3A CKD, it's part of the staging system used to assess the severity of chronic kidney disease. In Stage 3A CKD, there is mild to moderate kidney damage with a glomerular filtration rate (GFR) of 45-59 mL/min per 1.73 m². This indicates the kidneys are functioning at a reduced capacity, but the disease hasn't yet proregression. 

1. Stage 1: Minimal Kidney Disease - There is kidney damage with normal or high GFR (≥90 mL/min per 1.73 m²). 

2. Stage 2: Mild Decrease in Kidney Function - There is kidney damage with a mild decrease in GFR (60-89 mL/min per 1.73 m²). 

3. Stage 3: Moderate Decrease in Kidney Function - There is a moderate decrease in GFR (30-59 mL/min per 1.73 m²). 

4. Stage 4: Severe Decrease in Kidney Function - There is a severe decrease in GFR (15-29 mL/min per 1.73 m²). 

5. Stage 5: End Stage Renal Disease & Function Less than 10 percent - This is the most severe stage, where kidney function is significantly impaired (GFR <15 mL/min per 1.73 m²), and renal replacement therapy such as dialysis or kidney transplantation is usually necessary. 

It's important for individuals with CKD to monitor their kidney function regularly and work with healthcare providers to manage the condition and prevent further progression.
